Ok, so we are stumped. We built a custom registration system 5 years ago and have processed 10's of thousand's of registrations without any issues. In the last two weeks, 3 customers (of thousands) have had their check-out amounts sent to our credit card processor at 100x the correct amount. A $450.00 program registration was sent to Beanstream as $45,000.00.

We did a server migration in May but again, there have only been 3 incidences of this occurring.

The system was built by DNNhero, but unfortunately, Aderson is now away for a month.

We have had a very experienced person on this for 2 days and he remains stumped (as is Beanstream)

Does anyone have any thoughts? Much appreciated.
