Hi I've contact helpdesk about this already but I'm trying to find a solution in the meantime as my site is live and I keep getting these errors. "Error reported: Unknown Select Message Type CAUSED BY A non-empty path is required" This is the message from WorldPay in their Callback failure e-mail. If anyone has an idea for the fix then please let me know. Alex is very busy I think so I thought I would try here to solve the problem myself
I see Alexander is already answered you in helpdesk, from another side could you call WorldPay support and ask them to explain this error message. Error messages comes from their system, it is not bad to know what EXACTLY does it mean.
