Errors while opening CSS Forms Builder
So I started using FB today and was having work fairly well. A couple of things confused me at first (how to edit a form after it's built - my guess is manually viewing the code). So I went back and forth re-creating my form until I thought it was right. At a certain point I decided to save what I was doing as a preset in the type of form and in the design. The first worked like a charm. The second gave me an error (saving_custom.... image that's attached) at first I cancelled the save but after pressing save again it went through. So I closed it.
I didn't like how it turned out so I tried opening FB again and now I get the error in the second attached image. I removed the extension and reloaded and replaced the needed files provided by WA.Still having the same issue. Now I can't use FB.
