First, we have a user that made a payment at registration and it was successfully charged at authorize.net. However, it was not updated in CBSubs. The basket shows up with the "Pay" button in the backend. But when we try to make the payment it says "The payment basket has no gateway associated so it can not be paid manually". How do we account for this payment?

Second, there have been a couple of other issues with payments. A user went through the registration process and it charged her card but did not put anything into CBSubs and did not display a confirmation page for her. She then did it again, same thing. Then tried a third time and it finally completed. The problem here is that Authorize.net took 3 payments from her, but CBSubs only showed the last one.

But I did want to ask if there were any other reported issues like this?

And if you can think of anything that might cause this behavior?

For the first question I really need you to answer the part about "How do we account for this payment?". CBSubs won't let us put the payment in because of the error I described. And Authorize already has the money.

EDIT: I just looked at the errors in the history and there are a disturbing number of errors about duplicate transactions (approx. 70 in 3 weeks). Any thoughts on what might be causing this? The only other error exists because of a plan issue that I corrected.

And, if CBSubs cannot take payments like this, it should be able to. What if the internet was down to authorize.net, but they could still run his credit card via the phone lines? This would be considered an offline payment. Problem is, your offline payments do not allow for credit cards. This is a rare but realistic situation.
