Hi,
I'm developing the website locally with some third-party components and YooTheme Builder.
The currently installed Joomla! version is "4.2.8"
PHP 7.4, PHP 8.0.x work without problem. But switching to PHP 8.1 produces this error:
Deprecated: mb_strtolower(): Passing null to parameter #1 ($string) of type string is deprecated in C:\laragon\www\project\libraries\vendor\joomla\string\src\phputf8\mbstring\core.php on line 114
I observed, that previously Joomla had a similar error with PHP 8 and then it was fixed

What happens if you disable DJcatalog?

It is probably one of your extensions which causes this error. Could you check the call stack?
