I am testing OSCMax V2 RC2 and trying to get paypal to work correctly. The transaction works correctly going to paypal, passing the right amounts, etc, but when the payment is made and it tries to return to my site, it comes up with this error: Fatal error: Cannot redeclare class order_total in /home/MYSITE/public_html/includes/classes/order_total.php on line 13
I've turned the auto return on, and off and tested, I've also tested with the IPN on and off.
I tried with the IPN parameter set to mysite.com/checkout_process.php and mysite/checkout_success.php with the same result. It is my understanding that the passback is supposed to be checkout_process.php for the gateways to work, including paypal. My other gateway (2checkout.com) works correctly during the passback.
I would like to use paypal if possible, as I do a fair number of international orders, and CC's are too risky with that.
