@Krinkle Looking at the trace I do not see how this is related to Special:MyLanguage (feature of core nowdays). Could you either fix the title/content or explain. Please also justify the "Unbreak now" and be explicit if you expect the Language team to address this.

The codfw switchover will need read-only mode, and these errors kind of block that.

I'd considered it "very high", FWIW.

Ok, but the conflict with title and the stack trace remains. Must I assume that title is wrong and stack trace is right?

Some referrer URLs for log entries are like "?title=Special:Translate&group=X&action=page", with the API call URL is "/w/api.php?action=query&format=json&meta=languagestats&lslanguage=de", which has the error.

Other URLs include things like "/wiki/Special:MyLanguage/Translation_requests" and "/wiki/Translation_teams/sah".

We can probably ignore Special:Translate referrer URLs, since it's just an interactive JS page. The /wiki/ URLs are a problem though.

Confirmed. I can load https://www.mediawiki.org/wiki/Special:MyLanguage/News without problems now, when setting XMD to codfw and read-only mode.
