Does not logout

three things
1 the WP sync does not work. It gives an error to turn off sync to allow people to log in.

2 Users log in and yet cannot get to pages. States they need to log in even though when
clicking on Member login the persons profile shows stating they are logged in.

3 i also removed all cookies and tried different browsers all show logged in which is very strange.

users do show up in users for wp after registering.

It is updated to the latest version both WP and Membership.

The page I need help with: [log in to see the link]
