We’re having the exact same problem (as is one more person), so this clearly isn’t an isolated incident, so I have to say that someone else being told to make a new thread as if mine’s already resolved when it’s not is not really encouraging.
I tried deleting and reinstalling, but nothing’s changed.
I did see that someone had this issue before (here) and that the suggestion was to clear the browser cache, but that didn’t work either, and when I tried to do the solution suggested of closing out and not touching anything in the editor, I didn’t see any “Settings saved” toast.
The fact it uses the standard “.entry-content th” and “.entry-content td” classes without modification for better specificity was the problem. I had other plugins/modified parts of my theme that messed with that, so it caused a clash (specifically, the text wouldn’t respect the margins I kept trying to input with Tableberg because it was following margins for something else that used .entry-content td). I’ve gotten around it now by using custom CSS and selector {}, but if I hadn’t known how to use CSS I’d have been hosed.
