This is marked as “Solved” so you may not get any more responses here. Did you try to add a new field after you turned off your plugin? The fields won’t reappear. I had to import them from a copy of the site on my local machine.
So what I did was turn off all of my plugins. Then after I turn one on I go to save a field. I was able to do so until I hit the Google Forms plugin, then all fields disappeared. That’s when I knew it was the culprit. I find there are rarely problems with this plugin…
Hope that helps.
