BuddyPress.org

i have a buddypress/mu install that i’m working on that i could use a little help.

when a user logs in the plugin checks to see if they are in our database and if the password is good or not. If it is, it automatically creates the user into wordpress using their email, username and password.

The problem i’m having is when i create their blog with

wpmu_create_blog($domain, $path, $title, $user_id, $meta, $site_id);

it creates the blog, usernamexxx.domain.com but doesn’t have any styling to it and says

Error 404 – Not Found

Am i missing something?!
