[SOLVED] Order Quantity Deducted twice

Problem: When a customer orders a product the quantity gets deducted twice in my inventory. Also, the customer gets 2 mails for the same order. However, only one order is placed and the customer is charged once. I sell products in small quantities so this is very crucial.


Solution: The problem was in EBS payment gateway code. Order update function of order.php was called twice in order.tpl file.
