I've just setup my first Concrete 5.4-Site and also migrated my existing messages.po. Things work fine, my german nternationalization shows up correctly. But when i return back to the dashboard after a few hours or over night, Concrete5 switches back to english.

One way to solve this and get back to german translation is to clear the cache.
But i can't ask my customer to reload the cache first every time he logs in.

Any hint or simular experience on this subject?
