Hi again @igears,
No, nothing, the only difference is the payment gateway so I guess thats that is the problem. i have contacted our current payment provider and asked them if they can have a look.
That is a wise step. It is possible the issue is related to your payment gateway, their support team stand a better chance at providing a possible solution to this issue.
Please keep us updated on how this goes.
In the meantime, I’ll go ahead and mark this thread as solved.
