Please go to our site: mccla.org, scroll down the home page, and click the blue "Please sign our guestbook" button. A new window will open. Go ahead and fill out the form and hit the 'Post Comment' button. You'll see that you get an 'Invalid Data: Please try again' message.
If you're signed into the system (there are only five of us who have user login id's, you can use the guest book and it posts the comments. But that's not the intention here- we want guests who are just visiting the site to be able to sign in.
The Guest Book feature was working beautifully previously (I'm a new Admin here) and we're using WordPress 3.9.1.
I'd be grateful for any ideas on how to get the Guest Book working again!
