Cant see profiles

Hi all, can someone tell me why I cant see a profile when I click on it (after it's set-up) it goes to a broken link... you can see the dev site at www.drinksafela.com/partynetwork pls set up a profile and then see if you can see it. It all looks fine til I try and view the profile. All else looks good so far
