This just started happening when we upgraded to the newest version of Gravity Forms (188.8.131.52). We're getting an error in gravityforms/js/conditional_logic.js?ver=3.4.1 that says: "gformIsHidden is not defined".
Something that could be contributing to this error is the fact that the form is initially set to 'display: none;' and only appears when the user clicks on a link in the footer, which causes the form to appear inside of a tooltip.
Here is a link to the site: http://buccanpalmbeach.com/
And here is a screenshot of the error: http://buccanpalmbeach.com/images/conditional-logic-error.jpg
Any help you can offer would be greatly appreciated! Thanks in advance...
