Hello.
After an update from Joomla 4.0.6 to 4.2.7 on a client site, a few SPPB modules were not displayed anymore. (caches empty, CSS compression disabled ...). So I updated also SPPBuilder 3.8.7 to 4.0.7 : The hidden modules were not back.
So, finally, I tried a restore with Akeeba, from a backup before any update : site completely broken . Nothing displayed in frontend or backend. Only this message : Class "Joomla\Plugin\Behaviour\Taggable\Extension\Taggable" not found
Now, I just got back my site after a complete re-install with Akeeba/kickstart, in a new folder, and after deleting all the database content.
DB : 10.5.17-MariaDB-1:10.5.17+maria~deb11-log PHP : 8.0.27 Joomla : 4.0.6
Do you confirm SPPagebuilder is supposed to work with Joomla 4.2.7 ? If yes, why some SPPB are not displayed anymore after the Joomla update ?
