Hi All,
I'm setting up a new cart with 1.3.8a and have installed the payment module for "Paypal - Payflow Pro - gateway" and I can't get it to authorise a credit card payment.
How can I debug this and find out where the problem is ?
Is this the right module to be using ?

Any help would be really gratefull, this is the last step in getting this working.
Thanks.
