slide in does not activate. Gravity forms only other plugin installed.

The slide in does not activate. I've tested multiple settings (to rule out setting issue), multiple browsers, incognito, cleared cache, etc.

It has not worked once, so I'm assuming it is a conflict between the theme (headwaythemes) and the js used to trigger the slide in. Is there somewhere I can access the js code so I can test?

Is there another solution?
