Ich habe leider von der Materie sehr wenig Ahnung und kan mir nicht weiterhelfen. Hat einer von Euch einen Tipp was dies bedeutet und was ich tun muss, damit ich mich wieder einloggen kann? Bin verzweifelt.....

Lieben Dank und schöne Ostertage!

Kann es sein das dein Provider auf PHP7 umgestellt hat? Um das Problem zu beheben müsstest du auf phpBB 3.2 updaten.
