This is the site: http://www.legalmarketingadvantage.com/ (please do not fill out the form).
When you click on the submit button the arrows just spin. The message will be sent if everything is filled out correctly but nothing happens with the form. Same thing with errors, it just spins even though it should be showing the errors.
The odd thing is if I put the same EXACT WordPress installation (SAME theme, same plugins, db, everything) on another server the form works just fine. I also get no errors in the console but I do get this odd things showing up in firebug: http://screencast.com/t/zn07Okqm (which I think is called from controller.php on line 14: if ( 'GET' != $_SERVER['REQUEST_METHOD'] || ! isset( $_GET['_wpcf7_is_ajax_call'] ) )
I had the same issue with another installation on the same cpanel and when I moved the site everything worked fine. So I am not sure what could be causing this issue.
PS: It's on a host gator VPS and the cpanels on the same server work fine and I already tried the deactivate all plugins and use another theme thing. Newest version of CF7 and already tried a fresh install...
