I've looked through the posts on here and I can't find anything that addresses this issue.
I've created a donation form that uses the PayPal Pro add-on, when the PayPal feed is enabled, the form will not submit to PayPal and displays this error "There was a problem with your submission. Errors have been highlighted below." However, there are no fields highlighted and I cannot find any problems with the form. When I remove the PayPal feed the form works properly. I've looked in the Developer console on Chrome and I can't find any issues there either.
The problematic form can be found at http://www.aalove.org/donate/
The site is running Gravity Forms 1.7.6 and WordPress 3.5.2
Any help would be much appreciated.
