Hi,
I'm really not that clever when it comes to Paypal. I'm trying to get my ListingPro Paypal payment page working but I just cannot get the live payment system working. The sandbox works fine. I've spent hours trying to resolve this issue. Can someone please talk me through how to get the correct signature API credentials for my Wordpress site please. Many thanks
Ian
