Notes not saving

I have two websites where notes are not saving. The one I am posting about today is http://www.whsseniorparty.com. I found a support issue suggesting that the collation of the database tables might not match (http://www.gravityhelp.com/forums/topic/notes-arent-saving). They in fact did not, and so I made them all the same, and that did not fix anything. I tried switching to the twenty-ten theme, and the notes still did not save. I tried uninstalling all plugins except gravity forms and the gf paypal add-on, and that did not fix the problem. I truly don't know what else to try. I really need to resolve this issue. Thanks for any help anyone can provide.
