Myself i can access my admin without any problems to my own dashboard and can access all the dashboard in the network using my admin acces.
when a member try to sign up on his account the are redirected to this page
http://dashboard.webfeminin.com/wp-admin/?c=5

instead of
http://recettesetcuisine.webfeminin.com/wp-admin/
You don’t have permission to view this blog. Please contact the system administration

As you can see here no members appear
http://webfeminin.com/members/
i must use the special *Users Widget* on my front page to see the members and they are all redirect to http://dashboard.webfeminin.com/ and not to the member profile
their is 35 members (inside the button to the left) but it say : *Sorry, no members were found.*
