Just started blocking unblocked posts & pages

WP Members v 2.8.2, WP v 3.5.1
I have a few posts. All are unblocked. I have a page with posts page which is also unblocked. It has been working fine. Now all of a sudden, when I’m not logged in, my posts on the page say “this content is restricted to site members and I must be logged in, etc.” I have double checked each post to make sure all are unblocked and also double checked the page with posts page to make sure it is unblocked. Help anybody please as to why this just started happening! Thank you.
