(posting this on behalf of User:Minisarm): Although "MediaWiki:Categorytree-num-empty" [0] is localized at translatewiki.net [1], that doesn't seem to work at Romanian Wikipedia. Instead of "fără conținut" (Romanian translation) we are being shown "empty" in the Category namespace (see here [2] for instance). [0] https://ro.wikipedia.org/wiki/MediaWiki:Categorytree-num-empty [1] https://translatewiki.net/wiki/MediaWiki:Categorytree-num-empty/ro [2] https://ro.wikipedia.org/wiki/Categorie:Categorii_de_redirec%C8%9Bionare
When was it translated? If it's after Oct 27 this is invalid due to bug 62861 https://wikitech.wikimedia.org/wiki/Deployments#Week_of_October_27th
The tw page dates back to 2011. The ro. one was deleted on Oct 24.
Cause is https://ro.wikipedia.org/w/index.php?title=MediaWiki:Categorytree-member-num&action=edit FYI: I found this by using uselang=qqx on [2].
