I originally was going down the road of setting up WHCMS provisioning, but decided to scrap that and go straight with Pro Sites.
I have Pro Sites set up and domain mapping set up. I selected Pay to Blog, because I do not want to offer a free level at all.
When I go to the "checkout" page test site I set up it asks me to login in order to upgrade. There is not option to create/purchase a subscription.
What am I doing wrong?
