Hi, I am in the proces of migrating a site from j3.10.8 to j4.1.2. I followed Ofi's video https://www.youtube.com/watch?v=u6hy9Xepotg on how to migrate under Helix framework, everything ok but my SP Page Builder is dead. Had to desactivate all plug in for the migration to happen.
If I go to SP Page Builder, I have a
500 behavior::tabstate not found.
Normal : plugins are not activated
Now, If I reactivate the plugins, it gives me an error message and kills all my administrator.
0 Call to undefined method Joomla\CMS\Application\AdministratorApplication::isAdmin()
So, what should I do to have my SP Page builder running again?
