Paypal hand off token https://lizzie-borden.com/storeFront/pp_confirm.php?token=EC-4F
the store appears to working correctly until the point were you go from Paypal interface back to the PS 4 interface were paypal has handed a token to confirm process of payment cycle. Once you click the "Confirm" button in PS4 while it is on the "pp_confirm.php" page with the attached token information it errors on the "pp_success.php" page with the error of the page is not redirecting properly. sending attached screen shoot along with the two pages in question.
Further more if you do not click the confirm button on the PS4 page once redirected back, no trans action is completed but if yo do click the "Confirm" button in PS4 monies are transferred to and from their respective accounts. But the error message is received and the PS4 still has the cookie set like there was no transaction and the purchased item is still in the cart when you view it.
Hope this is enough information.
