[Gelöst]Wenn ich eine neue Basic Page erstelle kommt Fehler: The website encountered an unexpected error. Please try again later

Unerwartet kann ich keine neue Seite mehr erstellen. Sobald ich sie aufrufe kommt der Fehler: The website encountered an unexpected error. Please try again later. Bitte um Unterstützung.
Beste Grüße
