Internal Server Error

This plug in is causing customers to get an “Internal Server Error” message after checkout is complete instead of the purchase confirmation page. Their orders are in fact completed but the customers don’t know that so they place the order again. Eventually they give up, not knowing that they have placed the order multiple times. This happens with credit card purchases using PayPal Pro and Authorize.net. Additionally, no confirmation emails are sent to the either the customer or my seller email address. When I deactivate your plug in everything works fine.
