Hi Paul - thanks for getting back to me so quickly.
Good news about Helix 3!
Bad news about SPPB 3.8 though - it does work on the couple sites I've experimented with upgrading to Joomla 5, but if I turn on error reporting I see lines and lines of errors.
The problem is - I've build 180 plus sites that use SPPB 3.8. I've tried the new Page builder 5 and it just dosent work that well. And I assume I can't just upgrade from SPPB 3.8 to SPPB 5.2.
I can't believe there aren't a lot of other people who don't want to switch over to the new page builder.
So my next questions is - what do I need to do to get SPPB 3.8 to work with Joomla 5?
