The Unified Community Platform (UCP) is a new technology platform using an upgraded instance of MediaWiki, the software powering all wikis. For more information, see Help:Unified Community Platform and this support article.

Bugs[]

List of specific issues, errors or faults with the new platform.

Users[]

  • User Activity tab on Community Central shows something like cumulative total edits (global plus local to that wiki?) of user for each UCP wiki row.[1]
  • Signatures are truncated to 256 characters
  • The user masthead is lazy loaded and causes jumping.
  • Changing the user masthead on UCP wikis won't refresh the cache on non-UCP wikis.
  • User pages aren't auto-created when you join a UCP wiki.
  • Some disabled accounts are incorrectly marked as non-existent on UCP. (screenshot) (zd#940019)
  • User mastheads often don't appear (screenshot).
  • When editing your profile masthead there is no "discard unsaved changes" button.
  • For at least one user (w:Thread:1880256), their avatar keeps wanting to change to an older one. This bug stretches across all Fandom wikis, including pre-UCP ones (does not seem to happen if avatar was set before UCP existed).
  • If a user is promoted to bureaucrat, it will always show the "Bureaucrat" tag on the user's profile, even if they step down later.
  • The user masthead doesn't show the "My Favorite Wikis" list.
  • Wrong images show up after you left click an image and click to go to next in sequence in an article.
  • For users who choose one of the default avatar pictures on legacy except the human form (an earth, for example), that avatar picture doesn't show up on their user masthead (it still shows up on their posts).
  • After migration, the lists on Special:UserProfileActivity are not ordered chronologically. Possibly they are ordered by order of migration.
Unregistered users
  • Fixed Unregistered users' wall posts have no indication which IP posted the message (this information appears temporarily on Special:SocialActivity). The avatar and "A Fandom user" text leads to User:Null.
    • The avatar and text now link to the contributions page of the correct IP, in most cases.
  • Unregistered users have no message walls associated with their IP, therefore there is no way to leave them a message, including a warning.
    • Staff reply We're currently working on improvements to the experience around anonymous posts - you're quite right that it is not great at the moment, and hopefully we can get those tweaks live pretty soon!
Fixed issues
  • Fixed Staff reply User preferences are incorrectly changing when changed on a UCP wiki[2]
    • Staff reply The preferred editor preference was successfully transitioned to handle the two modes of the 2017 Editor, rather than the discrete editor options of the legacy platform[3]
    • Staff reply Creating a UCP wiki (and other UCP actions) should no longer reset user preferences[4]
  • The UCP user profile edit count is now really fixed (not sure what was fixed in previous update).[4]
  • Fixed Staff reply User edit count doesn't sync with either local or global edits.[5]
    • Staff reply The bug causing local edit count and global edit count to get confused on UCP profiles is now fixed.[6]
  • Fixed Disabled account message does not appear in contribs page of disabled account (MediaWiki:Edit-account-closed-flag)
  • Fixed Special:UserRenameTool does not rename account on UCP wikis. You can use Special:UserRenameTool on individual UCP wikis, but it does not affect it, despite giving a success message.[citation needed]
  • The "Free form" bio is not so free form: All newlines are collapsed into a single line (screenshot).
    • Staff reply By free form, I meant not constrained by a specific field question, not put it in literally whatever format you want. That's what your About page is for.[7]
  • Fixed The post count in the masthead sends you to your Special:Contributions page instead of to your Special:UserProfileActivity page.
  • Fixed Special:UserProfileActivity shows only recent activity.
  • Fixed There is no Special:UserProfileActivity for unregistered users, despite their activity logged temporarily on Special:SocialActivity.
  • Fixed Unregistered users' article/blog comments do indicate which IP posted the message, but in a weird way. The avatar leads to the IP's userpage, which gives an error. The text leads nowhere.

Editors[]

  • Staff reply Adding a video to an article from the editor is not implemented.[8]
  • Categories are not shown in Visual editor unless you go to Categories UI from menu.
  • Editing a section generated within a transclusion produces unexpected results. VE doesn't even properly support edit section yet. (ticket #932006)
  • Visiting a red link or non-existing page in a UCP site defaults with an "EDIT" button instead of "CREATE", which is pre-UCP behavior. (ticket #932146)
  • The gallery builder search feature for images on UCP migrated wikis return old images since over a year back or irrelevant results. [9]
  • After migration, editing an article causes Infobox galleries not to be displayed. (both, Visual- and Source Editor). Workaround: purging the page may fix it for that page.[10]
  • For UCP fandoms, there is a space bugs if you switch from Visual Editing to Source Editing, and vice versa. Example : Original source editing is | style="text-align: center;" | 03:38:00 . If you switch again to Source Editing after switching from Visual Editing, it becomes | style="text-align: center;" |03:38:00 . The space disappears sometimes if you switch them. There is a space bugs between after second vertical bars
  • Some mobile browsers may have trouble editing in the UCP Desktop Mode Editor even with "add features and media" toolbar and "Describe what you changed" boxes doesn't have a Expand/Collapse button.[11]
    • In addition, opening the mobile keyboard may cause the UCP editing area and the toolbars to incorrectly appear overlapped in some mobile browsers.

Visual Editor

  • Editing a page causes all data to disappear. The only accessible way to recover it is to use the source editor on the dropdown of the 'edit' button. (But can be then switched to visual mode without making it to disappear)
  • Interface color scheme doesn't adjust well for wiki color scheme. This can render portions of the UI nearly invisible to users.
    • Example: When editing a table in visual mode, two chevrons appear. One indicates the row and the other the column. To insert a new row/column, users must click the appropriate chevron (> or V). However, for wikis with light color themes, these arrows (above selected cell and to the left) are nearly invisible. This can trick users into thinking there is no way to insert new rows/columns. (w:Thread:1856782)
    • Users have reported problems in both dark and light themes. (w:Thread:1856782#22)
  • No autosuggest for edit summary - discourages repetition of long explanations.[12]

Source Editor

  • Source editor has issues where the text caret is displayed in the wrong position from the true caret, when there are over 1000 lines. (w:Thread:1877174)
  • While creating a new blog post, the preview feature glitches and shows the result of a missing blog page. The link to navigate back to editing is also not present. This causes loss of all content unless the user uses the browser's back button. (Steps to reproduce, ticket #1049435)
  • If you use the autocomplete function to complete a template name after double curling brackets for transclusion, use the keyboard arrows to choose one of the dropdown options, and press enter, it will insert the full template name, including the namespace. For example: You're typing: {{Quo... Than you chose the dropdown option "Quote" with the keyboard. It will insert {{Template:Quote}}, instead of {{Quote}} (ticket #1006563)

Preferred editor

  • Fixed When on UCP, changing my preferred editor to "Source editor" (2010), changes my preferred editor to "VisualEditor" on Legacy wikis (and also disables "View source on threads"). When on Legacy wikis, changing my preferred editor to "Source editor" (Classic) (or enabling "View source on threads"), changes my preferred editor to "VisualEditor - source mode" (2017) on UCP. [13] (ticket #976793)
See the entire behavior:[14]
Setting UCP Editor Legacy Editor
VisualEditor (UCP/Legacy) 2017 Editor (visual) VisualEditor
Classic rich-text editor (UCP/Legacy) 2017 Editor (visual) Classic Editor (visual)
Source editor (UCP) 2010 Editor VisualEditor
Source editor (Legacy) 2017 Editor (source) Classic Editor (source)
VisualEditor - source mode (UCP) 2017 Editor (source) Classic Editor (source)
  • Staff reply This is on our list to fix - hopefully we'll be able to get this cleared up soon! Unfortunately, I don't have a workaround to suggestion.[15]
  • Can be seen as fixed now that legacy wikis practically don't exist anymore.
Fixed issues
  • Fixed The source code editor is not sized correctly when editing in the User: namespace (screenshot).
  • Categories and images do not auto fill anymore in source code editor.
  • Fixed Source editor has to be continually selected
    • Staff reply We're working on getting the preference fixed to work with the change from discrete editor options to mode selection.[16]
    • Staff reply The preferred editor preference was successfully transitioned to handle the two modes of the 2017 Editor, rather than the discrete editor options of the legacy platform[3]
  • Fixed Categories don't appear for Source Editor in preview.
  • Show changes is difficult to discover and takes extra steps, because you need to click the "Save Changes..." button first.
  • Fixed A help notice for links is never permanently dismissed in the Source Editor nor the Visual Editor.
    • This appears to be fixed 2020/4/28

Templates[]

  • The UCP VisualEditor doesn't support the preloadparams [X] url parameter. (w:Thread:1828522#26)
  • There seems to be an issue where the same infobox gets listed multiple times as an option in the editor's visual mode. It is not yet clear what triggers this. (w:Thread:1839523)
  • Template parameters inside infobox panels are not available in the graphical interface when adding the infobox to a page. (w:Thread:1840944)
    • Staff reply Fortunately, I can confirm this is already on our list to review and fix, though I don't have an ETA for when the team can get to it.[17]
  • If typed template as subpage (example: /something), it will use template /something instead Pagename/something
  • Tag <infobox> produces a pair of empty paragraphs, one before and another after it, that add unnecessary vertical empty space to articles. See details and workaround.
Fixed issues
  • Fixed Global template transclusion (e.g. from Community Central) is not working.
    • Staff reply Release today fixed interwiki transclusion[18] - May 12, 2020

Files, images, and videos[]

  • Staff reply The full range of copyright scenarios for image uploads does not display, making "This is my own work" the only option.[8]
    • This may be inaccurate as the UCP Special:Upload Licensing menu doesn't contain a choice "This is my own work" and many choices show up which are very close to the pre-UCP list, but none have the associated templates are created (unlike pre-UCP wikis). The closest choice to "This is my own work" that appears is "I created this image myself." which points to the Template:Self which is not created.
  • Videos in infoboxes: when a video is put in an infobox, the play icon is enlarged and moved down, nearly doubling the size of the infobox (screenshot). Workaround: adding a gallery in the page (outside the infobox), even if only one image, makes the video thumbnail inside the infobox display correctly.[19]
  • Videos in galleries have messed-up images (screenshot).
  • Adding a YouTube video can fail when the description includes content blocked by the global spam filter. An error appears in the top background: "Fatal error: bit.ly (Block #471260)" (ticket #983568)
    • Non-UCP wikis currently ignore the filter when adding the video, but that code to bypass it is missing from UCP wikis.
  • Adding a new YouTube video can cause black borders to be automatically generated in the video thumbnail.[20]
    • Staff reply We're currently working on a fix for this - I don't have a specific ETA for when it'll go live, but hopefully we will be able to apply it to previously affected videos as well.[21]
  • OGG-Vorbis audio files do not show audio player UI and just give a link (wikitext example: [[File:audio_file.ogg]]). See w:c:sin-city-diaries:File:Sin_City_Diaries_intro.ogg
    • You can see the audio player UI (and the audio will play), if you render as Preview while in the Source Editor.
    • Update: Ostensibly fixed. However, the player UI has another issue: it renders as a non-responsive white bar if it is embedded in collapsed content. (Ticket: #973822. For an example, click "Expand" in this article section and scroll to the Audio Box. Ticket submitted on September 13, 2020.)
  • Submitting a link to a YouTube video with an identical title as another will cause the pre-existing video to be replaced, even if it links to a different video. (ticket #931840)
  • Renaming/moving a video results in an error due to "new file extension does not match its type". (ticket #931840)
  • Moving (renaming) an image file page can cause the file itself to disappear. (ticket #932479)
  • Slider galleries in UCP display video thumbnails too low, not centered as pre-UCP sliders do. Image files appear to be centered correctly. (ticket #932643)
  • Links from images ([[File:IMAGE.jpg|link=SOME_PAGE]]) doesn't work, always links to images.wikia.com image URL.
  • Borders for images do not work. When adding a border such as [[File:IMAGE.jpg|bordersize=medium]], the border appears in the editing preview, but once the edit is published the border is not there.
  • Uploading an image from Special:NewFiles, if MediaWiki:Licenses is empty, inserts {{undefined}} as the licensing template. This is almost certainly not a valid licensing template in practice. (ticket #968597)
  • The file page no longer has separate tabs for file information and the file history.
  • The mass uploader in the new editor tends to freeze after uploading the first image in queue and will either not complete or resume after waiting 3-5 minutes.
Fixed issues
  • Fixed Rendering images with vignette URLs, like https://vignette.wikia.nocookie.net/central/images/1/19/Getting_Started_icon.png/revision/latest/smart/width/53/height/53?cb=20190606105944 doesn't work, shows up as a link instead of an image
    • Staff reply Fixed in July 2, 2020 release.[22]
  • Fixed Uploaded images (GIF/PNG) can't have transparency. (w:Thread:1828128)
    • Staff reply This is a known bug — there is a ticket and a fix is presumably in the works.[23]
    • Staff reply Should be fixed.[24]
  • Fixed When trying to scale images past their actual size, instead of becoming larger they just get a white background where there should be an up-scaled image.
    • Should be fixed due to transparency fix.[24]
  • Fixed Whenever a file is replaced with a new version, the new version's upload date shows up on the previous version.
  • Fixed Thumbnails in the "Trending pages" section of the "Dynamic Categories" layout of category pages, AND in the "Popular pages" section on the wiki right rail, all these thumbnails used to show the wrong image (image in thumbnail is not on the linked page) w:Thread:1959144.

Admin actions[]

  • Fixed Bureaucrats can't promote others to Content Moderator or Rollback.
    • Staff reply Bureaucrats can now properly promote users to the Content Moderator and Rollback positions.[25]
  • Fixed Bureaucrats don't have block permissions. Therefore, one bureaucrat can remove another's admin rights and block them, making it impossible for them to unblock themselves.
    • Staff reply We just need to globally grant bureaucrats block rights. [That's been added] to our list! (Ticket #1024058)
  • Content Moderators, Discussions Moderators, and Rollbacks cannot demote themselves. Bot accounts also cannot remove that bot flag from themselves.
  • Administrators cannot delete or move user pages, unless they manually insert ?action=delete into the URL to delete the user pages, or change the URL to Special:MovePage/User:<Example> to move the user pages.
  • Administrators cannot disable blog comments on blog articles. Users also cannot disable blog comments on blog articles that they created.
    • This has been mostly fixed by the new (disablecomments) permission, though non-administrators still cannot disable blog comments on blog articles that they created.
  • Bureaucrats may also fall victim to autoblocks if an abusive Bureaucrat revokes their Administrator flags and blocks them.
  • Administrators cannot edit user talk pages on wikis with message walls enabled. Any attempts to edit the user talk pages will redirect the Administrator to the message wall of the said user.
  • Users with the (deletedhistory) and (deletedtext) permissions can no longer view the deleted histories and their associated text for pages that they cannot undelete. For example, Administrators cannot view the histories of MediaWiki messages that they can't restore.
  • Administrators cannot restore deleted blog posts by other users. (ticket #1001345)[26]

Special Pages[]

  • Special:Diff - Page exists but just doesn't work. It just takes the user to the landing page.
    • Special:Diff takes you to wikisubdomain.fandom.com/?diff=ID, which, unlike on the legacy Fandom platform, does not work. You would have to visit wikisubdomain.fandom.com/wiki/?diff=ID for it to work. It's probably just a regression. (w:Thread:1860079#20)
  • Special:PermanentLink - Suspected similar issue to that for Special:Diff; definitely similar symptoms
  • The user list special page displays a lot of accounts who aren’t confirmed to have accounts on Fandom.[27]
  • Fixed Special:ListUsers shows 0 members for most groups.
  • Fixed Special:ListUsers lists all users globally, rather than users who have edited on the wiki
    • Seems to be a new ListUsers page now, and no longer lists all users.
  • Fixed Special:MovePage - (Main) namespace not visible in list when trying to move a page from a non-(Main) namepace to the (Main) namespace. Workaround: select the Talk namespace, then move up one in the list to (Main). (ticket #933619)
  • The Sitename namespace does not support Visual Editor. Due to this, the edit button text also says "Edit Source" rather than the usual "Edit".

Local wiki header[]

  • Fixed Page count can become wrong due to bug (that may now be fixed) where moving a page would decrement the "Pages" count in the local wiki header. Compare "Pages" count with pages shown in Special:AllPages.
    • Staff reply Renaming a page no longer reduces the page count by 1[4]

Interface and design issues[]

  • When jumping to an anchor within a document, different than the currently viewed document, the anchored text starts beneath the Fandom bar and requires scrolling to actually see it. (ticket #933952)
  • On screens smaller than 768px the global navigation becomes unusable, with search, user dropdown, and notifications disappearing (screenshotRelease Highlights - March 11, 2020).
  • Special:Contributions looks much messier than it does on non-UCP wikis:
    • The fieldset in Special:Contributions (or "Activity") is not modernized.
  • Search bar now require 4 letters to show the link suggestions, instead of 3 letters. (ticket #1020340)
  • The "Related Wiki" thing that shows up when using Special:Search is going off the edge of the page (screenshot).
  • When linking the first character on the line in the VisualEditor the little caret isn't positioned correctly (screenshot).
  • The toolbar is collapsed on every new wiki you enter.
  • There seems to be less room between paragraphs.
  • Profile editor on UCP interacts poorly with dark themes
  • <body> is missing the oasis-dark-theme class on dark themed UCP wikis
  • Notification bell (for Discussions follows and likes) drop down has larger icons and text, but drop down rectangle is same size, so less entries are visible than previously.
    • Staff reply A bug report has been filed. Whilst the icons are larger, this does not mean that less content fits within the box as reported.[28]
  • Changing the border style for gallery images through Visual Editor does not work. By default, it is set to small, but it never updates when changed. https://prntscr.com/rw4az7
    • Adding the source bordercolor="transparent" or bordersize="none" may accomplish what you want.
  • UCP Galleries sometimes inserts a timer class randomly that replaces gallery images captions. The page shows correctly for a couple of seconds but is replaced by JavaScript.[29]
  • In the Admin Dashboard, when requested to "Upload Video" as a task, the interface displays a page which only allows image uploads. Uploading an image does not dismiss the task.
  • The save dialog contains a copyright notice. This notice links to a local page that is not created automatically and therefore shows as a redlink. (this thread)
  • If Theme designer is used to customize link colors to something other than what is provided by one of the default themes, only the colors of internal links are modified. External links and interwiki links do not obey the customization. This behavior doesn't occur in non-UCP sites. This is on the list of fixes to be implemented.
  • Temp files uploaded to preview in Theme designer are not flushed, even if changes are not committed with "Save, I'm Done". These files may appear as "Temp_file_(ten digit generated number).png". This is on the list of fixes to be implemented.
  • On some wikis, on the top Search Bar, the text that says "Search SITENAME..." will not always display the sitename correctly. This occurs on wikis when its name contain certain characters in it (ex: apostrophes, ampersand and more). Example here and here.
  • The Latest Discussions area under Fan Feed (bottom of the page) does not show the author of the Discussions Post.
  • Hidden categories display as non-hidden in the list below the page, but are properly hidden in the list above the page. The preference to show/hide hidden categories does not affect the list below the page. (Zendesk #979231)
Fixed issues
  • Fixed The editor uses cursor: pointer instead of cursor: text like it should as a text editor
  • Fixed The word "community" is automatically added to the end of a wiki's title.
    • Staff reply Per the answer you got on Discord, no to the community thing.[30]
  • Fixed The search bar semi-uncollapses when on your message wall page.
    • Staff reply A bug ticket has been filed, thanks for reporting this.[31]
  • Fixed New UCP wikis are missing the Main Page link on Discussions.
    • Fixed at some point in late April 2020?

Global CSS Loading[]

  • The CSS for galleries is not always loaded. While this can be fixed by purging the impacted pages, it should load properly the first time.
  • The order in which the individual global CSS files are loaded is problematic. Styling for specific features use CSS rules with the same specificity as the general CSS rules. As such, which rules get applied depends on the order in which the files are loaded. In some cases, the feature-specific CSS is loaded before the general CSS. This results in those features not displaying as intended.
    • Entries for level 2 headers in the table of contents have both a number and a square bullet. At the time this entry was updated, the offending selector is ".mw-parser-output ul" and the selector that should be applied is ".toc ul".
    • Image collection tabs in non-Europa portable infoboxes don't display centered as intended. At the time this entry was written, the offending selectors are ".mw-parser-output ul", ".mw-content-ltr ul", and ".mw-content-rtl ul". The selector that should be applied is "ul.pi-image-collection-tabs". (Thread:1861732)
    • Level 2 headers have insufficient space between them and preceding content. At the time this entry was written, the offending selector is ".WikiaMainContent h2" and the selector that should be applied is ".mw-parser-output h2". (Thread:2016324)

Extensions/feature issues[]

  • The Recent Wiki Activity module shows UTC time only.
  • The Discussions activity feed doesn't work on UCP, it renders as plain text instead of creating the feed.
  • No "Founder" tag for founders.
  • UCP uses "Sysop" tag where legacy wikis used "Admin" tag.
  • Need to configure Special:BotPasswords to use AWB with UCP (w:Thread:1922264).
    • This is most likely intended behavior.
  • Starter Lua modules are created with an incorrect content type assigned to the pages. This prevents users from editing the modules as the editor detects this as an error.
  • Custom Achievement tracks from migrated wikis don't use the correct name in modules or the Leaderboard, even though the MediaWiki pages that store them do. (They use Edit Count track ones instead)
Fixed issues
  • Fixed Cross wiki links using [[w:c:something|label]] sometime go to international version of wiki (maybe only Polish?) and not one without language code specified. i.e. [[w:c:animanga:Diomedéa|Diomedéa]] (Diomedéa) goes to https://animanga.fandom.com/pl/wiki/Diomed%C3%A9a instead of https://animanga.fandom.com/wiki/Diomed%C3%A9a?redirect=no
    • Looks to have been fixed at least with specific example above.
  • Fixed Syntax highlight does not actually color the text and adds the page to Category:Pages_with_Syntax_highlighting_errors. (this thread)
  • Fixed The <math> tag is broken. Using example code from Help:Math gives an error like: [afadac929aededa761793f49] Caught exception of type Wikimedia\Rdbms\DBQueryError

Media integration

Message Walls

  • All links pointing to Message Wall:Username are redlinks since those pages don't seem to actually exist anymore.
    • Was marked as fixed, but it seems to still persist. Though for users who joined the wiki when it was on legacy - the links are not red. Probably because those pages exist.
  • Adding ?debug=1 causes the masthead and profile tabs to completely break (when on your user and activity pages) and nothing whatsoever to show up on your Message Wall page.
  • The Message Wall toggle in the AdminDashboard didn't immediately take effect
    • Staff reply Bug report filed.
  • After the Message Wall feature is Off the Message Wall tab on the profile is gone but is not replaced with a User Talk tab like with what happens on non-UCP wikis.
  • Fixed Message wall notifications don't appear when the user is on Discussions (article/blog comments notifs do appaear though).
  • Message wall notifications aren't sent via email.
  • Fixed The "User talk" namespace no longer redirects to the "Message Wall" namespace.
  • Fixed Usernames above posts next to avatars on Message Walls do not link correctly. You would expect them to go to "User:USERNAME" but go to "User:USERNAMEUSERNAME"
  • Fixed Deletion of messages or threads has no effect.
  • Custom fonts are not working.
    • Probably just needs adjustment of the CSS.
  • An attempt of editing own message (wall or article comment) often gives an error: "There have been a problem editing the message. Please Try again." for non-admin users, even within the 24 hours timeframe. This seems to happen more frequently when the message contains URL or pictures. (Screenshot)
  • Normal users who deleted threads or messages from their own wall, either cannot hide them or cannot view them (this was switched at some point).

Mobile Skin

Notifications

  • The message in the notification dropdown puts a white line between the "X has written a message on your wall" (or whatevs) and the title of the post.[citation needed]
  • Reporting my own post on my message wall caused the notification icon to go haywire, and the mail icon disappears. (ticket #931103)
  • Fixed The notifications dropdown is absurdly wide.
    • Appears to be fixed, long titles are now truncated with an elispis instead of displaying their full length.
  • Fixed First 10 notifications are loaded for all types, while the rest are loaded only for discussions replies and upvotes, what makes other notifications to disappear and never show up again.
    • It's now fixed on UCP wikis, when the user is not on Discussions.
  • Clicking on a MW notification doesn't mark it as read when the username of the wall owner contains spaces.
  • The difference between read and unread notifications is barely noticable.
  • The number of notifications isn't updated until page reload.

InfoboxBuilder

  • After following the flow to create an infobox (Press "New Page" button, input "Template:TemplateName", Select template type as "Infobox") you get taken to the Special:InfoboxBuilder/Template:TemplateName but the infobox builder never loads.
    • Staff reply Bug report filed — thanks.[32]
  • When modifying Section Headers the text explaining Collapsible Section Headers is duplicated (screenshot).
    • Staff reply Bug report filed — thanks.[32]

CSS

  • @import
    • Fixed Personal global CSS requires use of a full URL and load.php
    • Due to how site CSS is loaded, does not work from Wikia.css
    • Syntax highlighter/checker recommends using HTML link tag instead. Apparently this is the case even on the legacy platform.
    • Importing custom sliders from the Dev Wiki doesn't work.
    • Using a relative URL for an import in a non-english wiki fails, due to the loader looking for the file under the main domain without the language part.[33]

Menus

Blogs

  • Fixed Only admins are allowed to comment on blogs. The blog's author is also allowed to leave comments on their own blog.

Emails

  • Fixed Migrated UCP wikis are not sending emails when someone edits a page a user is following even if that's turned on. Though this is not happening to wikis that have always been UCP just migrated ones.

Inter-wiki links

  • Trying to use a URL with the beginning of the page name that matches an interwiki link (even if name uses accented characters, i.e. pokémon: will match pokemon:) will remove that part of the page name and also will not allow a page to be renamed with that part at the beginning of the name. (w:Thread:1994102)

Problems regarding converted wikis[]

  • UNICODE characters, such as emojis and UNICODE-fonted characters, turn into question marks when the contents are converted from Special:Forums to Discussions (and supposedly on converted message walls and comments too).
  • In some wikis wall threads weren't migrated (at all or partially) and therefore are not accessible in any simple way.
    • Staff reply Some wikis' wall contents will have to be re-migrated.
  • In at least one wiki, the original wikitext pages of migrated wall threads got deleted.[34]
  • Previously deleted threads appeared back after the migration.[35]
  • Old links to threads and replies may be broken, due to a failure in establishing the redirects.[36]

Missing features[]

Some features that exist on non-UCP wikis are not currently available on the new platform, and are listed below.

  • Ace Editor
    • Staff reply CodeEditor is dependent on the 2010 WikiEditor, which we are currently exploring to see if we can refactor into the 2017 Editor[37]
  • Fixed Achievements
    • Staff reply Coming soon, according to MisterWoodhouse.
    • Staff reply Currently are available.[38]
    • Creating new achievement tracks is not implemented.
  • Fixed Custom CSS
    • Staff reply[3][24]
    • Global (from CC) and personal scripts and CSS are not imported.
      • Staff reply Personal global CSS on the UCP is now available by editing a personal CSS page on ucp.fandom.com which is serving as a temporary Community Central style wiki for the UCP until CC can be transitioned at the end of Phase 1.[24]
  • Classic Rich-Text Editor
  • FlaggedRevs
    • No status.
  • Message Wall Greetings
  • Fixed MultipleUpload
    • MultipleUpload has been added in the form of Fandom's custom in-editor UploadNewImages extension, but it doesn't support file renaming or setting file descriptions/upload summaries.
  • New Image Galleries
  • Semantic MediaWiki
    • Staff reply In final acceptance testing.[39]
  • Special:Templates
  • Welcome messages
  • Transition animation for collapsing elements.[40]
Previously missing features
  • Fixed Arrays
    • Enabled by request.
  • Fixed Article comments
    • Staff reply Article Comments are not yet enabled.[30]
    • Per previous blog posts, Article Comments are being rebuilt to not rely on retired code. They are not currently on new UCP wikis, as they were not deemed critical for this stage of Phase 1.[41]
    • As of the June 12th update comments are available again and can be toggled on/off (default on) via the Admin Dashboard[42] or on a specific page by admins via the editor.
    • No UI or page for tracking adding new-style comment contributions. (w:Thread:1890754#28)
      • Now handled by the new Special:SocialActivity
  • Fixed Blogs
    • Staff reply Blogs are still being evaluated. We've heard a lot of great feedback regarding their role in different communities and we have not come to a final decision on blogs yet.[43]
    • Staff reply We're still working on what the blog system will be for the UCP, but Blogs are going to be on it.[44]
    • Staff reply As I've confirmed several times, Blogs will be coming to the UCP and the development of that feature is ongoing.[45]
    • As of August 8, 2020 blogs are live on UCP wikis.
  • Fixed Custom JavaScript
  • Fixed DPLforum
    • Staff reply Since the Forums retirement has not happened, DPLForum was not sized as a Day 1 requirement.[47]
    • Staff reply DPLForum extension is now installed on the UCP.[4]
  • Fixed Global Lua Modules in Scribunto
    • Staff reply Loading global modules from the legacy platform will fail.[49]
    • Staff reply The Global Lua Modules have been migrated to the UCP. I don't know much about them, but I'm told that some of you will be very happy about this :)[50]
  • Fixed Loops
    • Staff reply I am seeing Loops as slated for full rollout of the platform, which will be later in Phase 1. No ETA on when that release will be, as it has many dependencies.[51]
    • Staff reply The Loops extension is now available on the UCP![24]
  • Fixed MediaWiki:Newarticletext
    • Staff reply I can confirm that it will support it.[52]
    • Now working.
  • Fixed Mobile editing
    • Staff reply A specific editor for mobile users is coming![53]
    • Staff reply The Mobile Editor is now LIVE on all UCP wikis![6]
  • Fixed WikiFeatures
    • WikiFeatures is now integrated into the Admin Dashboard.
      • Not as reliable as legacy wikis, though.
  • Fixed Gadgets
    • Staff reply The Gadgets extension has been ported to the UCP.[54]
    • There are numerous issues with the extension on UCP wikis. Text on Special:Gadgets and Special:GadgetUsage is unlocalized and MediaWiki:Gadgets-definition is uneditable.
    • As of 2020-08-13 MediaWiki:Gadgets-definition is editable, but all pages are still unlocalized.
    • As of 2020-08-18 all gadget pages seem to be working as intended
  • Fixed DisplayTitle magic word ({{DISPLAYTITLE}})
    • Only formatting changes (such as capitalization) are allowed, likely due to the MediaWiki $wgRestrictDisplayTitle flag being automatically enabled in new wikis.
  • Fixed Special:Community
    • Staff reply This extension isn't available on the UCP yet, but will be added soon.
  • Fixed TabView (but no longer available on request).[55]

Known changes[]

Some changes are not bugs but intentional changes, and are listed below.

  • Dev Wiki additions -- due to changes in class names and other functionality, some Dev Wiki modifications need to be updated to work with UCP while others may be obsolete. See DEV:UCP.
  • Staff reply Localization strings have changed from custom Fandom translations built up over years on the forked 1.19 platform to the standard MediaWiki translations on 1.33, so some of the terms which non-EN users see will have changed.[8]
  • The masthead doesn't include other details like location, birthday, occupation and gender. That's by design. We switched to a freeform bio with the Profile changes.[56]
  • Special:WhatLinksHere does not work on Message Walls
    • Per our discussion earlier this week, that is not a bug. It is due to the new Message Wall design no longer being MediaWiki custom code.[57]
  • Wikis are now based on a different 'Starter' wiki
    • Staff reply The old starter wiki is NOT the source of new wiki spinup.[58]
    • The starter for the new UCP communities is in a private database. It's not accessible by outside users. Shortly before feature releases for UCP, I will add any relevant additions that capitalize on newly available tools.[59]
  • New Tags appear in Special:Contributions and Special:RecentChanges.
  • User tag text on user profiles is now in MediaWiki:user-activity-group-* and not whitelisted. Also, the User tag for "Blocked" is missing.
  • Editing own message (wall or article comment) after one day can't be done anymore. This was changed in order to prevent potential abuses of the system (such as changing the context of the replies). (Screenshot)

Removed features[]

  • Chat
    • Staff reply Chat will not be ported to the Unified Community Platform. [60]
  • CategoryIntersection
  • CreateBox
    • <createbox>...</createbox> doesn't work. Please use Inputbox instead.
  • GoogleDocs4MW
    • <googlespreadsheet> tag doesn't work.
  • Image placeholder
    • [[File:Placeholder]] doesn't work.
  • Special:Insights
    • Staff reply This maintenance tool that highlights unclassified templates, non-portable infoboxes and other maintenance issues on a wiki won't be available on the UCP, since it saw only little usage by communities on the Fandom legacy platform. These maintenance tasks can still be accessed through MediaWiki's special pages.
  • Shared Help
    • Staff reply We're replacing those transcluded local Help pages with redirects to their Community Central sources.[61]
  • Wiki Activity
    • Staff reply No plans to re-implement in UCP. May try to change RecentChanges to meet similar needs.[3]
  • Wiki Polls
    • Staff reply Fandom's wiki-style Polls (AKA AjaxPolls) are not available on the UCP, and wikis that migrate to the UCP will not have this feature available. The global usage of the feature was not sufficient to merit the required effort for replicating the feature on the new software, given some rather tricky technical issues. Discussions has a built-in polls feature which can be used instead. For archiving poll data for historical reference, this Dev wiki script has been raised as useful.
  • Special:FilePath
    • Replaced by Special:Redirect/file
  • Category Exhibition
  • Special:Disambiguations
    • removed from UCP because it is no longer part of MediaWiki software, it was removed years ago.[62]
