Paypal Auto-return problem

Hi, so I’ve got Paypal Express Gateway activated (live mode). I set up the auto-return feature within Paypal. So after the user pays, he’s returned to a specific page on my site (directcombatives.com/confirmation). But when he’s returned, it brings up the Protected Content page. Yet, the page is not protected!

(The page is not listed under Membership Pages in Options).

How can this be resolved? Thanks.
