Membership acces denied problem

Ooops i did something wrong at my site.

Some how, when i login to my site as a member the site url say its protected, and i am not sure what i did wrong ....

Any ideas what i did wrong when i did try to setup membership ?

I have every thing under positive rules in membership, i dont understand what i did activate or did click on since i have no acces to do any thing on my site as a member ...... heeelp please.

Edit:

I think it was the url groups that made the problem, it was checked.
