We have a site that we use GF to do payments for golf tournaments (we have 5 a year).
The first two worked great. But this third one seems to have issues. The form accepts the fields but half the time it doesn't redirect to the Paypal page for payment. It drops the user into the "You've not paid yet" landing page. I think this happened after one of the upgrades.
I can pm you an account if you like. Thank you!
