Hey All - Just a heads up to let you know to be careful when updating the free version of Formidable Forms from 6.0 to 6.1. I am an FP Elite user but the standard plugin is required and it broke the redirect portion of the forms on one of our sites.

We use FP to gather a zip code from the user on very simple forms throughout the website. We have +300 of these simple forms, since we have to track a taskID along with the zip code submission to a second form, which gathers the users information.

All of these simple forms started displaying the standard "Success" message versus redirecting to the second page as intended. 
I have an open ticket with the Formidable Team on this as well, but wanted to warn against it in case you have the same type of form setup, and automatic updates enabled in WP.
Thanks,
Mark
