Hello everybody,
I need an help about the Paypal email notification order. How can I editi it?
When that email come it contains in the order description the name on my hikashop item and the product code. How can I delete the product code?

Hi,
You'll probably be able to do that by setting the "Display product code" option to NO through "HIkashop->System->Configuration->Display"
