Good evening Yesterday I upgraded to Joomla 4.4.12. I have the latest version of Helix Framework and PageBuilder Pro The system still runs on PHP7.4.  If I change to PHP 8.3 the website crashed. For this problem I made another topic several months ago.
when I want to visit the website I get the following order:
Compile Error: Declaration of JoomShaper\SPPageBuilder\DynamicContent\Model::offsetExists(JoomShaper\SPPageBuilder\DynamicContent\mixed $offset): bool must be compatible with ArrayAccess::offsetExists($offset)
I tried to restore a backup from the website and the database, setting it back to 4.4.11 Although the back up is set back again, the error is still there. The website can not be viewed because of this error. There is no dynamic content in the website.
