I have installed Gravity Forms Version 1.6.12, however the form editor does not work.
After some investigation trying to find the cause (plug-in or theme), i found it to be somehow WooCommerce (Version 1.6.6) related.
I am using WordPress Version 3.5.1.
When I click on a form field type say 'Name' or whatever, that field is not added to the form. To the user it looks like nothing happens when you click on the button. This affects all the field type buttons, so i cannot add any fields to my form.
However, upon deactivating WooCommerce , the functionality is restored.
Are you aware of this issue.?
I raised the issue with Gravity Forms - they advised me to raise the issue with WooCommerce!
