Hi Steve, I have OPC all installed and working great! Paypal express is the only payment module I have at the moment, but it seems that when I pay with paypal express, after I confirm and then it redirects me to checkout.php?action=process_confirm, checkout_process.php ends up being a blank page. It's weird but the payment goes through, also when I hit the back button from the blank page, my contents from my purchase are still in my shopping cart... Any help would be appreciated!
here are the errors I get from the "blank page" (checkout_process.php)
