AGB 2.3.1 won't post! Just sends you back to Sign guestbook

Hey, my AGB v. 2.3.1 won't post entries. WHen you hit add entry it returns you to a blank forum to sign the guestbook. It wont preview it either! can someone help me? url is http://cousinunjust.freecoolpage.com/guestbook/index.php For admin. the username and password is Test/123. Any one have any ideas?

I've had that problem too - it's really annoying. I had to go back to Advanced Guestbook 1.01! I had the problem with version 2.3 and 2.3.1. The guestbook works fine on my local server and pretty much everywhere else I tried it. My guestbook can be found here. I may be moving my site to a different server anyway so the new version should work there.

the reason is simple.
your php version is not compiled with this option

--enable-track-vars
