Wont save changes

I’m having this issue as well. However, the only section that won’t save changes is the “Manage Forms” area.

Any ideas?

Yes that’s the same problem I was having but I never received a response.

I am also having this problem. I received an ‘error undefined’ pop up box. Then I tried disabling Fancy Admin AJAX Abilities as was suggested in another thread. Now when I try to save or delete in manage forms, I get a 404 page and the changes aren’t saved.
