So I'm not completely sure what went wrong, but something has been seriously messed up on my website. Its ampedforeducation.org.
I had a blank visual editor when I tried to edit a page, and after checking the forums decided to deactivate all plugins, then reactivate them one at a time and delete ones that made the visual editor blank. I only ended up deleting two plugins, both of which I thought I didn't need, but apparently one or both were necessary to make the website look normal. Unfortunately I have no idea which plugin I deleted besides Gridster. Is there a way to fix this? Can I revert my website or wordpress to an earlier time somehow? I really have no idea what to do!
