I just added Gravity Forms to my new site and can not get it to work, error "Ajax error while saving form", I can not create a form, save it, the one time I was able to create a form, it would not allow any fields.
I have done the following:
Deactivated all plugins
removed Gravity Forms and reinstalled
added to wp-config.php define('WP_MEMORY_LIMIT', '64M')
robooted the server
Cleared the cache in Firefox
Changed Theme to Twenty Eleven
Creating new form icon just spins and then error "Ajax error while saving form"
At this point I have no idea what to do, Windows server 2008, Plesk 11
