On my 1st domain, I tried GD core, with Elementor. It worked OK.
On the GD pages, Elementor easily inserts the GD widgets.
On the non-GD pages, Elementor easily mixes GD and non-GD widgets, exactly as I wish.
And it works fine until today.
On the same hosting, I created 2nd domain, bought the full set of GD, installed it, and now Elementor stopped working on GD pages, although it continues to work on non-GD pages…
The error message on trying to start Elementor editing the GD pages is : “The Content Area Was Not Found in Your Page”
(Elementor relevant explanation is here:

Any ideas?
