If you type domain.com/mu/wp-admin in the address bar, you are redirected to domain.com/wp-admin and, of course get an error stating that the directory is not on the server. If you type domain.com/mu/wp-admin/ (notice the slash at the end) or domain.com/mu/wp-admin/index.php it will go to the admin section. I've installed MU on a lot of sites, but I have only noticed the error twice recently. How can I fix it? Thanks.
