Ich habe die Betreuung von einem Projekt übernommen, dass bei 1und1 gehostet ist. Da der Kunde einige neue Funktionen nutzen möchte habe ich versucht, die Versionen 4.1.3 oser 4.1.6 zu installieren. Die Installation klappt soweit auch, das Frontend wird auch ohne Probleme angezeigt. In das Backend kann ich mich jedoch nicht einloggen. Ich erhalte folgende Fehlermeldung:

Daraufhin habe ich versucht beide Versionen mit dem Dummypackage zu installieren. Gleiche Fehlermeldung.
