I have 28 members on my site and when I am not logged in and click the members tab it shows the first 20 by default on page 1 of the member's directory. When I click on page 2 nothing happens. I try to search for a member and nothing happens. Also, when I try the "order by: alphabetical, last active or newest registered" it does not work and returns a blank page.
However, when I am logged in all of the above problems go away. I am using the social theme, buddypress 1.6 and wp 3.4.1.
