Hello, even though i uploaded helix ultimate framework plugin and template i get this error message. I tried different php-versions.....joomla 4, Helix.....everything is updated. What can I do? Plugin is enabled.....

I migrated a copie of the original website to joomla 4......before everything worked fine.

Thanks for your help.
