page builder pro - joomla 5 compatible?

Hi, even works on Joomla 6.0.0 ;]

But you need, a current version.

If you are in the Joomla upgrade process, ignore messages that Joomla 4.4.x may display to you about SPPB plugins, and upgrade Joomla from 4.x to 5.4.

And yes, all infos you will find is the above link (documenation). Just read or translate (DeepL).
