Hi Pino,
unfortunately, I don't have access to a shell on that hosting.
I gather that the message is not severe, though it's still irritating to get on login.
I entered several standard (?) locales, de-DE, C.utf8, de-DE.utf8, en-GB.utf8, the warning persists though.
Any ideas?
Best, -f
Mhm, I could still not make that warning go away by any of the above means (on an English/German multi-lingual site, after upgrading to 3.0.62).
Any other ideas?
