URL for restricted page payment is wrong

Hi. I have successfully implemented a page restriction and a paypal button to pay. When you pay, the email is delivered successfully. The URL (expanded) delivered to the customer is incorrect, in a specific way, every time.

An example :

Suppose the page you want to buy access to is http://ondemand-education.com/corp/index.php/courses/siebel-universal-inbox-part-two/. You pay for it, and I expect you to receive an (expanded) URL like this:

http://ondemand-education.com/corp/index.php/courses/siebel-universal-inbox-part-two/?s2member_sp_access=XXXXXXXX#ondemand-education.com

But what you receive is actually this (note the mising “courses”)

http://ondemand-education.com/corp/index.php/siebel-universal-inbox-part-two/?s2member_sp_access=XXXXXXXX#ondemand-education.com

Which doesn’t exist and you get a 404 error. This repeats itself for every “course” we sell. This S2Member module being used with LearnDash (a Learning Management System plugin), in case that helps.

Thanks for any guidance.
