For a few days now, we've been having a strange problem where our "Default Language" no longer seems to be working correctly. We've installed a few language packs and update regularly via the "Extension Manager." Our primary language is also up-to-date, and there have been no updates.
The fact is:
The entire backend /admin#/
is suddenly in English. The same applies to the title of "User Directory" and "Private Discussions."
The last change made was a different mail provider /admin#/mail
. However, that works perfectly and shouldn't affect this?
Does anyone know what could be causing this?
