The Pro Sites description page says it has an option to allow front-end checkout, but I can't seem to figure out how to make that work. I've tried the option of using wp-signup.php?Pro+Site=1 or wp-signup.php?pro-site=1 (I've seen both mentioned in different places), but nothing looks any different. I can go through the signup process and never see any option to pay. There is the option for "Would you like to upgrade this site to Pro?" and I selected "I'm interested" but I still never see any way to pay during the checkout process. I've enabled "Pay to Blog" and that prevents the site from actually working when I sign up, but there still is no way to pay. I must be missing something or something must be wrong.
Just to explain what I want, ideally, it's for users to come to the site where I explain the paid service, they click "Order Now" to sign up, they create an account and pay, then they're taken to a thank you page with information about their site. I don't want to offer a free level, and I don't want users to be able to sign up for a username. So that's the end goal.
At the moment, however, I'm testing things and there's no way to pay even if I wanted to. I don't know what's wrong. Can you please help?
