When switching my website to PHP 8.0 I encountered the following errors:
500 error due to mb_http_input('UTF-8') which is an invalid value.
The GD extension functions return a GdImage instance instead of a resource breaking the thumbnail creation (and probably some other image related functions).
When the create_img function threw an exception, the filemanager wouldn't show a (default) thumbnail (on any PHP version).
