I deactivated all plugins and the when I reactivated page-builder from site-origin the icon disappeared.
However, I got the “white screen of death” for my front end after reactivating all the other plugins again :/ The backend is working like it should, but the front end is gone.
I´ve done this before and fixed it via FTP som I´m not in panic, but it never happened with the backend still intact.
Suspecting the snippets plugin where I have PHP code or a cache plugin… what do you think?
