We have been having the same problems, after turning on the test mode and trying different configurations I came to realize 2CO does perform the direct return properly, The orders work if I have 2CO leave a link for the customer to click on but direct return just does not work. All the params are set up correctly.

My 2checkout module was working fine. Until recently, I found out that I stopped getting the order confirmation email if customers chose to pay using 2checkout. There is no order record in my zencart admin either. Any idea how this happened? Please help. Thank you.
