Provider wants to resubmit failed credit card payment and presses "Charge CC", but the following error appears:
Payment locked, E-Transaction couldn't be performed.
In the E-Transaction of the payment the following message appears: Error2: Server Error. Could not process payment data. Please contact Provider.
Until E-Transaction completes or finally fails by timeout the payment document is locked and thus can not be paid twice.
In order to resubmit payment manually, the following link should be used: [Unlock & Resubmit.]
It can be found on the Payment's General page, near "Processing Status".
Please note that in order to avoid double-charge, Provider first needs to contact processing center and make sure that this transaction is not in progress.
