ok, ok, so first, it seems, i have to to the steps as written 2 posts back, right? for now I cant even go to backend.
You know , the mass was also, when I upgraded the page to Version 4, those 2 pages had many errors that werent there before upgrade to V4. When I had V4 I had to fix those broken pages mannually and it took me hours. And this new page builder wasnt really use friendly. That's why I was glad that you told me that i can downgrade again, because V4 felt like a horrible experence. Now if I go back again to version 4 pagebuilder I am afraid again there will be bugs, I really feel cheated!!! not by you, of course.
