Hello, I found out the SP Simple Portfolio issue.
On Joomla 3.10.1 SP Simple Portfolio read the Text field on Database Table xxx_sppagebuilder (correct).
In the new Joomla 4.0.2 SP Simple Portfolio read the Description field on Database Table xxx_spsimpleportfolio_items (wrong).
For this reason SP Simple Portfolio isn't working anymore.
See the video and the 2 examples below..
