When checking out this morning, I got this message:

Exception Caught: '127', which means: 'Fraud Service Internal Error-- go to Reports tab to rerun transactions through filters'.

and the order did not go through (all still sitting in my cart).

Apart from the fact that I have no idea how to rerun transactions through filters in the "Reports Tab" - this payment was actually cleared through my bank and the money taken. I have sent an e-mail for support but am also posting here because this looks very VERY odd to me. In fact, this looks very much like a site hack!
