Shop läuft nicht nach Update von 2.6 auf 3.1

[netsuvi]

Habe soeben auf PHP 8.0 umgestellt, weil mein Hoster das so wollte.
Das update selbst ist sauber durchgelaufen. Der Admin Bereich geht,
aber der Shop bleibt leer.

In meiner phperror.log Datei sind jede menge warnings und dann eine Fehlermeldung:

Habe was herausgefunden:

Habe das Backup geladen und das update nochmals durchgeführt.
Ich habe das Popup nicht anzeigen lassen, weil Firefox das ja standarmässig blockiert.
Mit dem Popup läuft ja noch so einiges ab.

Artikel gehen, aber was noch nicht funktioniert ist die Anzeige der Kategorien.
Dass lässt sich hoffentlich auch irgendwie lösen.
