Sorry for not making it clear.
I'm trying to fix an issue for someone and am new to oscommerce.
Up to the middle of November he received an email of the store copy of the order.
I thought it may have stopped because of the worldpay callback issues.
As the order copy is sent if you use the Cash on Delivery option, this also made me think it was a worldpay issue.
He also had other issues with the callback on worldpay, and the fact it stripped out the buttons.
All of which your module solved.
Its a CRE loaded version of oscommerce so it's probably been modded somewhere.
However I'll try your suggestion.
Thanks for the reply and help, much appreciated.
