BuddyPress.org

My WPMU & BP is working fine. Even I am able to browse everything like forums, groups, activity with ease. I can create individual blogs as well & further I can post new topic. I am able to access those posts & blogs. But when I click on “Blog” icon on header I will get message like this

“Page Not Found
