I have followed the steps here:
http://www.shopsite.com/help/9.0/en-US/ ... alpro.html
Yet I am receiving a payment processing error code 10501, Invalid Merchant config.
I have the correct API username and password entered in to the Configure Website Payments Pro section and I copy/pasted the entire API certificate from Paypal. The Host is set to Live and not sandbox. Any ideas on what I am doing wrong? I can't tell if this is a ShopSite config issues or a PayPal issue...
Any ideas?
