Hi,
I am testing a new site and ran into a 403 forbidden error in a specific case with the PayPal sandbox environment.
I am using PayPal Standard to accept donations. If the user has a PayPal account the flow works great. Both IPN and PDT work without issue. If the user has no PayPal account however and attempts to pay with a CC, then the string that is passed back by PayPal results in the 403 error. I am not sure exactly what BPS does not like in the string nor how to configure it to allow this condition.
If I deactivate BPS, then the transaction completes successfully. I read the other threads on the BPS 403 errors but no of them seem to apply.
Running BULLETPROOF PRO 5.2.2.
Thanks for any guidance.
