I wish that I could help you but I am also receiving the same email indicating a PayPal IPN Invalid Process. I, the webmaster, and listed in the IPN Module to receive error messages.

My error emails seem to be also associated with the Shopping Cart. I have had 64 orders with no such error message for nearly two years. Then, as of 7/9/11, the error emails are arriving with every order. The good part is that the orders seem to be processed as always meaning that the store and the customer do not know that these error emails have started.

The latest one, this morning, is an example where the customer placed an order with an amount less than the minimum allowed. The program notified him, on the Shopping Cart screen, that the total amount was not enough. He then changed the quantity, proceeded to Checkout, and successfully completed payment, returning to the store per the PayPal instructions. The customer performed a very simple task in making a change to the quantity. However, I received two identical Invalid Process emails.

Does anyone have insight as to what might be happening? Maybe PayPal recently changed something which responds to IPN?????

Thank you for your help in resolving this strange situation!
