Membership Plugin restricting Page 2 of My Blog

My blog displays on my homepage, at http://nextgenresale.com/. If you click the "Older Entries" link at the bottom of the blog listings, it links to this URL (http://nextgenresale.com/page/2/), and it says that it's not available to the public (it's being restricted to members only).

I'm quite sure that I don't have this blocked specifically (I wouldn't even know how). Thanks!
