WordPress MU

Hello-
I know this is a dumb question but-
I have a blogsite on my MU which is in the database still but it is not listed in my admin panel.
This is a subdomain that the user had an outside domain going to
The outside name is listed in my admin panel but I can not get access to the backend of it and when I try to look at it, it takes me to the main page of my site
Both the subdomain and the outside domain show on the same level as my root in my ftp
How can I restore that database?

Yes I have the same problem. But with subdirectory blog

"This is a subdomain that the user had an outside domain going to

What plugin where you using to handle the outside domain for the subblog?

"Both the subdomain and the outside domain show on the same level as my root in my ftp"

Yes, that's what they are supposed to./ MU is one program to handle multiple blogs.

"How can I restore that database? "

You don't - they all live in the one single MU databsse.

Andrea,
Thank you so much for responding.
Vhost and directory enabled domain mapping plugin by Incsub, is the plugin I have installed.
Is there a way to get the data stored in the tables to show back up on the wpmu (it could be a different sub domain)?

Have you asked over at their forum? It's a paid plugin, so you get support for it from the person you bought it from.

Hard to say, since I use my own domain mapping plugin.
