Hallo zusammen, ich habe einen neuen Shop in der Version 5.0.1 installiert und bekomme beim konfigurieren im Backend häufiger an verschiedenen Stellen den folgenden Fehler angezeigt. Der Fehler lässt sich leider nicht immer an der selben Stelle reproduzieren. Manchmal sogar direkt nach dem Login. Oder beim konfigurieren der Versandarten. Woran könnte das liegen, hat jemand eine Idee? Viele Grüße Alex 503 - Service Unavailable Ups! Ein Fehler ist aufgetreten! Die nachfolgenden Hinweise sollten Ihnen weiterhelfen.
