Contao Backend und Frontend nach Update nicht mehr erreichbar
Hallo,
ich habe eine 5.0 Installation, die ich jetzt eigentlich auf einem Testserver updaten wollte. Dazu habe ich die Theme aktualisiert.
Jetzt snd leider Backend und Frontend nicht mehr erreichbar und schmeißen eine Fehlerseite raus: "Es ist ein Fehler aufgetreten"
Die Log-File sagt folgendes:

Damit kann ich nichts anfangen.
Kann mir jemand weiterhelfen und weiß, wie ich das wieder hinbekomme?
Lieben Dank im Voraus
