Error at checkout? Please help

Hello people!

I just made a test product for 1 dollar and made an account with my mothers information and used her card to charge a dollar...i come up with this error at checkout when i press " Confirm Order"

"This appears to be a duplicate transaction as it is an order for the same order amount in a short period of time. Your credit card has not been charged. Please check the order history, and resubmit in 5 minutes if this is a valid order."

I am having this error occur as well. I am using Joomla with the JooZen component which is ZenCart for Joomla.

The system is using Quickbooks Merchant Services and Quickbooks Payment module.

"This appears to be a duplicate transaction as it is an order for the same order amount in a short period of time. Your credit card has not been charged. Please check the order history, and resubmit in 5 minutes if this is a valid order."

From what I've read integrating ZenCart with QBMS is complex and difficult at best, anyone know how to solve this issue?

:censored:

I'm having the same issue with QBMS, same error too.

Anyone find the solution to this problem yet?
