Most Admin Bar Links Redirect to Homepage

Hi, when I am logged into http://scootervineburgh.info/wordpress/ as the admin using buddypress, the links from the admin bar redirect me to the homepage. The links that are broken include all of the ones that pertain to: activity, profile,messages, friends, groups, settings, etc. (every option under “my account”). Therefore, I can’t compose messages, check my inbox, etc. I have had this same problem using a variety of themes. When I copy and paste the links directly into the browser, it just redirects to the homepage. Any ideas….?
