Suddenly I'm unable to add another form to the newsletter feed. When I try to select a form from the drop-down, all I get is the spinning radial thingie just hanging there spinning. I already have one form added. I've disabled all plugins except GF, Wysija, and the Wysija GF addon. I'm using WP 3.6, GF 1.7.7, Wysija 2.5.5, and v.1.2 of the GF addon with Genesis 2.0.0 and the Agency child theme.
