Sprachenwechsel - Kategorien/Produkte offline

Hallo Leute,

wenn man im Shop die Sprache wechselt (z.B. auf EN) und danach wieder in die Standardsprache DE zurück wechselt, sind alle Kategorien und Produkte offline (offline.html). In der Sprache EN funktioniert es aber noch.
Erst wenn man Cache & Cookies im Browser leert, funktioniert die Sprache DE wieder. Das Problem tritt aber sofort wieder auf, wenn man zu EN wechselt.

Woran kann das liegen?

Seit kurzem haben wir diese Fehlermeldung. Vll. hängt es ja damit zusammen?
