@yenerunver, I’m sure this is too late to help you out, but since no-one is replying to these public support forums, I thought I would post the solution here to help others.

“The error you are receiving means that PMPro is able to make a one time payment, but fails when setting up the recurring payment. Usually this happens when you don’t have the ARB (Automated Recurring Billing) module added to your Website Payments Pro account. This is a separate “module” that you need to pay extra for with Website Payments Pro. Confirm with PayPal that you have this module activated. We’ve heard of some customers who have this module visible in their admin, but still had to call into PayPal to confirm that the module was active.
Some other things to look into. Can you make sure you have a “title” set in Settings -> General (silly thing that sometimes causes issues). And can you please test your recurring payments with an amount of $0.5 – $1 as anything below $0.5+/- might not go through Paypal successfully.
If you confirm with PayPal that the ARB module is active, the title is set, have updated the recurring price to $0.50 or more and are still seeing this error, let us know and we’ll perform some further tests. For that, we’ll need FTP access. You can share the FTP host/user/pass in a private reply.
I apologize for the inconvenience caused and we will be looking into adding better error handling/messages regarding this.
Thanks.”
PS: I was charged $97 for a membership just so I could see this answer on their secret forums. Not a great way to do business, guys! Hopefully this comment prevents other folks from being forced to pay this kind of money for something they should already have the answer for.
