Ich gelange in das Backend der Installation, jedoch lässt sich die Seitenstruktur nicht aufrufen. Dann erscheint sofort der oben genannte Fehler. Alle installierten Erweiterungen im Contao Manger habe ich auf die kompatible Version zu 4.13 angehoben. Die Datenbank ist aktuell. Der Contao Manager läuft ohne Fehler durch.

Woran kann es liegen, dass ich die Seitenstruktur nicht mehr öffnen kann?

Beste Grüße
