Problem with AJAX

Hello,

I seem to have a problem with using AJAX-plugins. I have tested almost every AJAX-plugin on this site, but not a single one has worked properly or at all. Obviously, there’s something wrong with my theme? (I used another theme earlier, and at least *some* AJAX-plugins were compatible then.)

Theme: http://www.refueled.net/lounge/go.php?http://www.refueled.net/downloads/peacemaker.zip

Best regards
