Alan from Anderson Zaks says:
Our new WPG software is now installed and working as expected.
There was a brief issue yesterday afternoon where two stage transactions were failing to re-connect resulting in transaction cancellation at the RedCardServer whenever Address Verification was invoked.
It turns out that was a result of my being over-cautious and leaving a backed up copy of a config file where it could still be found by the application.
I have backed out yesterdays change and re-applied it whilst moving backup copies to a more inaccessible location.
I can see, in todays log file, several transactions for Monad customers - all appear to be behaving correctly.
