PHP Version Update Problem

Hallo,

und ich hoffe in Allgemein war das hier richtig. Ich wusste nicht genau ob die Frage passt. Ich habe Probleme die Seite auf die neue WordPress Version zu bringen. Derzeit benutze ich ein Child Theme von den Main Theme Azeria für einen Kunden. Allerdings kann ich das Problem nicht gnaz verstehen. Die Version war auf 7.4 und ich wollte auf 8.3 erhöhen.

Dann spuckt er mir diese Fehler aus:

Deprecated: strpos(): Passing null to parameter #1 ($haystack) of type string is deprecated in /www/htdocs/w01526e7/kjw-nuernberg/wp-includes/functions.php on line 7300
