I experienced this error when using GF in combination with the "Admin Menu Tree Page View" (http://wordpress.org/extend/plugins/admin-menu-tree-page-view/). Disabling AMTPV solved the issue. I was only experiencing an issue on the admin side, and was unable to edit any forms, however I did not see any problems with the live form.
In my brief look, I do not see why there would be a conflict, though. I do not see AMTPV overriding any scripts. Below are the enqueue lines in the init action:
- js/jquery.biscuit.js (jQuery.Cookie Renamed)
Since disabling AMTPV fixes the problem, but the error is from a GF script, I'm just providing the information to allow both sides to investigate.
