Produkt: Tao Contao
Contao-Version: 5.6

Das Update erfolgte von Contao 5.5 auf 5.6

Wenn ich im Backend nun den Theme Assistant öffnen möchte, wird folgender Fehler angezeigt:

func_get_arg(): Argument #1 ($position) must be less than the number of the arguments passed to the currently executed function

Ich gehe davon aus, das ist der dazugehörige Log:
