Extension:CheckUser causes RecentChanges to not update.

As the title says, I cannot see the edits in Recent Changes, even with all filters removed. I can only see the edits when I go to the User Contributions page of the user account or the history of a specific page.

Here is the setup of my wiki:

Product	Version
MediaWiki	1.39.4
PHP	7.4.33 (fpm-fcgi)
MariaDB	10.4.20-MariaDB-1:10.4.20+maria~buster-log
ICU	65.1

I verified that no filters are applied at the Recent Changes and still nothing shows up, yet I know there are edits that were successfully made (such as here, for example--there are hundreds more made via the API in the last 7 days).

For added context, the Mediawiki instance where this is occurring was recently updated from version 1.35.8. Since that time, it appears that no edits show up on Recent Changes.

what's your $wgRCMaxAge setting value? you can also try to run Rebuildrecentchanges.php

I don't have $wgRCMaxAge defined in LocalSettings, so it should be the 90-day default. I did run rebuildrecentchanges.php and now changes before that execution do show up in Recent Changes. Unfortunately, any changes made after that (for example, this one) don't show up.

I just disabled all extensions and edits are showing up in Recent Changes now as expected. So now begins the task of activating them one by one to figure out which one was causing the problem. I'll report back after I do.

For reference, here are all the extensions/potential culprits:

wfLoadExtension( 'AbuseFilter' );

require_once "$IP/extensions/AmazonBookShow/AmazonBookShow.php";

wfLoadExtension( 'AutoCreateCategoryPages' );

wfLoadExtension( 'CategoryTree' );

wfLoadExtension( 'CheckUser' );

wfLoadExtension( 'Cite' );

wfLoadExtension( 'cldr' );

wfLoadExtension( 'CommentStreams' );

wfLoadExtensions([ 'ConfirmEdit', 'ConfirmEdit/ReCaptchaNoCaptcha' ]);

wfLoadExtension( 'CookieWarning' );

wfLoadExtension( 'Description2' );

wfLoadExtension( 'Echo' );

wfLoadExtension( 'EventStreamConfig' );

wfLoadExtension( 'Flow' );

wfLoadExtension( 'Gadgets' );

require_once "$IP/extensions/JobBoard/JobBoard.php";

wfLoadExtension( 'Maps' );

wfLoadExtension( 'Moderation' );

wfLoadExtension( 'MultimediaViewer' );

wfLoadExtension( 'Nuke' );

wfLoadExtension( 'OATHAuth' );

wfLoadExtension( 'OpenGraphMeta' );

wfLoadExtension( 'PageForms' );

wfLoadExtension( 'PageImages' );

wfLoadExtension( 'ParserFunctions' );

wfLoadExtension( 'Renameuser' );

wfLoadExtension( 'ReplaceText' );

wfLoadExtension( 'RevisionSlider' );

wfLoadExtension( 'SecureLinkFixer' );

wfLoadExtension( 'SemanticCompoundQueries' );

wfLoadExtension( 'SemanticMediaWiki' );

wfLoadExtension( 'SemanticResultFormats' );

require_once "$IP/extensions/SideBarLike/SideBarLike.php";

require_once "$IP/extensions/SideBarSocialButtons/SideBarSocialButtons.php";

wfLoadExtension( 'SimpleBreadcrumb' );

wfLoadExtension( 'TemplateData' );

wfLoadExtension( 'TextExtracts' );

wfLoadExtension( 'Thanks' );

wfLoadExtension( 'TitleBlacklist' );

wfLoadExtension( 'UserPageEditProtection' );

wfLoadExtension( 'VisualEditor' );

wfLoadExtension( 'WikiEditor' );

wfLoadExtension( 'WikiSEO' );

By the process of elimination, the culprit is...Extension:CheckUser! I even downloaded the latest version just to make sure (although I already had the latest that is compatible with MW 1.39).

I looked at the Extension Talk Page, and what do you know...I'm not the first to notice this problem! https://www.mediawiki.org/w/index.php?title=Topic:Xhg78xfk5hbwmu5g&topic_showPostId=xhg78xfk5l9yuy3o#flow-post-xhg78xfk5l9yuy3o. Guess I'll be disabling the extension for now.

Looks like the person in the other topic found an answer that worked.

"Thus, I decided to:

1. Disable the extension
2. Run php maintenance/update.php
3. Enable the extension
4. Run php maintenance/update.php again

"Lo and behold, everything is working just fine now."

For future reference also - when a job or defferedupdate related thing doesn't work, often the error isn't shown in the interface. The error can often be found in the debug log - manual:$wgDebugLogFile
