I just updated my site from Pro v 1.7 or 1.8 to 2.3. At first everything seems fine, but when I open a page to edit, as soon as I make a significant change to an element, or delete an element, all of the rows and columns in the editor disappear. If I save the page, the changes were effective, but still don't show up in the editor. When I leave and come back, they show up again, or if I refresh the editor, they come back up.
Also, Essential Grid and Revolution slider don't show previews in the pro editor anymore.
I've gone through all my settings and versions to make sure everything is compatible. I've disabled plugins and still can't seem to find a solution.
Sorry if I missed this somewhere in the forum, but not sure what else to try.
