Just started first time with Joomlashaper.
I installed SP Page Builder 6 on J 5.4. Helix ultimate is on. License key of SP integrated and activated.
So in Pages, whatever layout I try to import layouts or parts of Layouts >> "something wrong there".
The message comes within 2 seconds.
I tried with IMPORTING whole layouts and pages / parts like contact, always same issue. I also tried with another template.
Cachee of joomla is empty. php 8.3, everything on the server with plesk on a very new standard.
info.php tells me, everything is enabled, so there is no blocking from my server.
Who can help?
