I am running the PayPal app v.5.010 on osC 2.3.4 in Sandbox mode using PayPal Payments Standard. The payment process proceeds smoothly, and when PayPal returns to osC it shows checkout success. The problem is no confirming emails are sent.
I have planted “die” commands at various points in the checkout_process.php code and it appears that that the processing leaves checkout_process when it instantiates the payment class, never to return (about line 47). I have set the PayPal Auto Return parameter to both checkout_process and checkout_success and get the same result – no confirmations. It looks lie there are over 100 lines of code that never see the light of day.
How do I fix this?
