Need Help Asap, The Page Builder has stopped working, Specifically, the Little Tab on the left, which opens the block menu has disappeared. I would deeply appreciate directions on, either, 1. how to fix ? 2. where is the folder location ? 3. how to reinstall ? I have already tried, updating and downgrading php, also reinstalling other versions, as well as over writing files, I have 2 webs sites, it works on the test / staging site, but not the online site. Thank you in advance !
