Hey all,
Very useful thread, so thanks. If you’re still struggling, this may be your problem:
I was working on a site that had Google Analytics for WordPress installed (by Joost). The developer used this plugin to add Analytics.
Using the method outlined above (adding the UA event tracking code to CF7 additional settings), the form would not reset or show the “thank you” message.
I deleted the Joost plugin and added the UA tracking code to the footer manually. After that, everything works just fine.
So if you’re using any third party plugin to add Analytics code to your site, that could be the problem.
Hope that helps!
