BuddyPress.org

I am using WP 3.5.1 and BuddyPress 1.7.2 and have had a few users sign up in the past few days who have not received activation emails. On another site I own, I have the BuddyPress Pending Activations plugin installed, and it works perfectly, allowing me to manually go in and activate users who have not yet been activated or resend their activation emails to the address they used when signing up.

But on this site, I am completely unable to do this, as the BuddyPress Pending Activations plugin doesn’t work. I’ve deactivated all plugins and themes, and still have this issue. Any help is appreciated. Thanks!
