Ill tell you whats happening:
When you edit a page in sppagebuilder and hit save two thinks happen with the frontend editor:
the name of page becomes blank upon saving it
the permissions are removed and not visible upon saving it
Everytime I make or change content on a page I have to open it on the backend and give it a name again and set the permissions to public. That's just temporary until I edit it again and click save.
Also new: I am having trouble duplicating pages in SP Pagebuilder. If I duplicate a section in the backend editor I get a runtime error. Sometimes it allows me to duplicate the page, I go in and edit it and change the name of the page and content and when i save and close its gone.
I tried to reinstall sppagebuilder and no change at all. Now if I duplicate a page and rename it, it dissapears.
