Pages with pending changes (all these: https://de.wiktionary.org/wiki/Spezial:Seiten_mit_ungesichteten_Versionen) can't be edited or read - a totally blank page is returned.
Workaround is probably to review or reject the revisions before editing.
Is this T156310: Fatal error: Call to undefined method Revision::getText() in extensions/FlaggedRevs/backend/FlaggedRevision.php on line 480? At least that task is about a fatal in FlaggedRevs in wmf.9.
The error is the following:
Jan 26 10:36:07 mwdebug1001 hhvm: #012Fatal error: Call to undefined method Revision::getText() in /srv/mediawiki/php-1.29.0-wmf.9/extensions/FlaggedRevs/backend/FlaggedRevision.php on line 480
looking into logstash it seems this started yesterday just before 21:00 UTC:
which corresponds to the SAL entry
20:50 twentyafterfour@tin: rebuilt wikiversions.php and synchronized wikiversions files: group1 wikis to 1.29.0-wmf.9
I think this might be worth a rollback.
From a quick talk on IRC, @Joe recommended to rollback immediately to restore production immediately which is now complete.
T156310 mentioned that error earlier and there is a straightforward patch to it. Guess I will test it on beta cluster then production group0 and if all is fine move back to wmf.9 when done.
For now marking as a dupe of the other task that has the patch.
