BuddyPress.org

I use MU 2.9.2 subdomains and enabled root_profiles for buddypress 1.2.4.1, I did this by editing wp-config as stated on your help docs, now my admin profile link leads to ( http://example.com/admin/ ) and it give error:
” The page you were looking for was not found. ”
If I added (members) to the link its working, and for new members its okay [shown good without (members) in link]
admin only is messed up, so is there a way to fix admin profile link and keep the feature enabled?
