Not working on GF 2.9

It seemed to work up until version 2.9.x. I suspect there are different scripts that need to be loaded. The form submits, records the submission but does not complete on the front end and get the following errors in console:

Uncaught ReferenceError: gform_theme_config is not defined

I've tried to troubleshoot this myself without success.

Ok after much troubleshooting it works fine actually! My plugin for Gravity Forms Event Tracking was the culprit. The form will not submit with this enabled on version 2.9. I assumed it was the iframe plugin but it was not. My bad. Anyone else check your other plugins first by disabling them.
