WorldPay have a major upgrade scheduled for October 30th, in the UK at any rate, not sure about the USA, The main issue seems to be a change in the IP range for callbacks - as outlined here: http://support.worldpay.com/kb/reference/f...ml#storebuilder Does this affect us at all?
I have'nt got round to looking at this yet with Amember, I have checked out the oscommerce WorlPay and the module there does not use ip address checking on callbacks. Alex could give us an answer on this? ( lazy way) or peek at the code and see if it using an IP address to check if the callback is coming from WorldPay?
Just to say thanks to Alex for the usual efficiency, and supplied the update for the changes at WorlPay.
