members pay, but can't see restricted content

I’ve very recently installed s2member on my site.

I’ve set up to use all four membership levels. All four give users tha same access. The difference is in how they pay (monthly or yearly, etc).

When they pay and are directed to my welcome page, they click on the link to the home page and go there. But when they click on ANY link to restricted content, they are directed back to the welcome page.

I cannot figure it out.

Please help.
