Looks like l10n-bot has removed this message (and several others) from many JSON files in i18n/wikimedia/ in 0f3c6c9d83d3dcbda5cf545ba116d35f2d0cea90… in some languages, it was added to the JSON files in i18n/wikimediaoverrides/ instead, but only in some. I suppose rEWME80cd8c440fae: Move overrides to wikimediaoverrides json files (en.json and qqq.json) might be the root cause of this behavior?

@Raymond Can we do a full export from Translatewiki for this extension?

Actually, this has been broken for a while, probably shouldn't be a release blocker…

@matmarex Full export for WikimediaMessages done: https://gerrit.wikimedia.org/r/#/c/387553/

That restored a few languages (it, et, pl), but many more are still missing (e.g. he). Searching for "createacct-helpusername-url" in the repository gives 24 results, while https://translatewiki.net/wiki/Special:PrefixIndex/MediaWiki:createacct-helpusername-url/ has 58. Do you have any idea why the missing translations would not be exported?

Weird.... In translatewiki config the message get a prefix because it seem to exist in core. But it this still true? I cannot find it in Core per grep.

Furthermore: Translating via translatewiki does not add the wmf- prefix. Maybe this is the problem?

If this message is not longer part of core or other extensions I can remove the prefix and I guess that the problem will be fixed..

I did some history digging and it used to be in core, but was removed ages ago. See https://gerrit.wikimedia.org/r/#/c/61395/ and https://gerrit.wikimedia.org/r/#/c/62570/.

I think it is because some translations are marked as "FUZZY" because of "Namespace changed from the definition". Try to confirm it and wait for next update.

Any updates on this: is the issue still present? Is help needed to debug this?
