“Can’t Select Database” when moving servers

I just moved the site to a new server http://uterinesarcoma.org . I had gotten the admin area to work but not the site itself. After fiddling with a few ftp files, it’s giving me this “can’t select database” error message when I try to access it (below).

I have checked that in wp-config:

1) username correct

2) password correct

3) database name correct

Also, I’ved checked that the database tables are still there.

What can I do?

Can’t select database

We were able to connect to the database server (which means your username and password is okay) but not able to select the upmarket_uterines database.

* Are you sure it exists?
* On some systems the name of your database is prefixed with your username, so it would be like username_wordpress. Could that be the problem?

If you don’t know how to setup a database you should contact your host. If all else fails you may find help at the WordPress Support Forums.
