Hi
I installed a copy of the mainsite https://www.hlcollection.ch to https://www.room-concept.ch and upgraded to Joomla 4.4 and the latest SP Pagebuilder Pro Version.
Now the error "Class "JString" not found" shows on several pages in the frontend and also in the backend.

Thanks for support!
Cheers, Markus
