that error is coming from OPC. it's basically saying the hash has changed and i need to reload everything.

why it is doing that is anyone's guess.

empirical data suggests the square webPay and OPC do play nice together when properly configured. so why OPC is telling you that your order details have changed, perhaps may be better served over on the forum over there. i am not the OPC expert by any stretch.

best.
