I have "PayPal Website Payments Pro - Direct Payments" enabled but the module asks for "PayPal Express Checkout" enabled too , so I enabled that as well.
All I'm trying to do is to have one option that allows paypal processing on the background, without going though the paypal site. I thought thats what the "paypal website payments pro" does, however I wonder if it doesn't work unless my client has exactly that kind of service on his paypal account. (Currently he has "Paypal Payments Advanced")
