I am using ZC 1.38a and Paypal Payment Pro. Before I installed Super Orders 2.0 everything went through flawlessly. However, I had to print out every single invoice one by one in ZC, so I installed Super Orders 2.0 to batch process orders. Presently every thing is OK, except that a blank page appears after payment confirmation if customers check out with credit cards.

I found the problem occurs whenever I tried to pay by credit card through Paypal Payment Pro. The confirmation page is blank, and no email notification was sent out to owner or customer.
I tried using Debug Error Logging Utility to find the problem, here are the messages from the debug files:

[25-May-2010 09:32:35] PHP Warning: Division by zero in /home/content/xxxxxxxxxx(my directory)/html/includes/modules/order_total/ot_group_pricing.php on line 79

[25-May-2010 09:32:29] PHP Parse error: syntax error, unexpected $end in /home/content//xxxxxxxxxx(my directory)/html/includes/classes/super_order.php on line 557

Thank you for your reply.
