Here's a video of the issue in the Fantasy Grounds list. When trying to enter the idea, the Add button doesn't work.

Thank goodness I'm not the only one having this issue. I can't add a new idea from any browser or system.
My first idea submitted just fine, but then it stopped working and the Add button just does nothing. Had to have Moon_Wizard to add my ideas.
