Subdomains not showing in admin panel after migration

We recently paid to have our wordpress multisite migrated to bluehost on a dedicated server. When I ftp in, everything is the exact same (as our old host that everything is working fine on) in terms of file structure and the MySQL database. The only things that should have changed were the database name and password in the wp-config file. However, when I log into the admin panel none of the network admin stuff is showing. None of the subdomains are available. Bluehost support basically said they can't help because it's "unsupported"

I'm really out of options here...
