Whay am I getting a database connection error?

Hello,

I just installed Multi- DB and I am getting a database connection error.

The current database is installed on a remote host. All the 16 new databases are on the same remote host.

This script: http://twbnet.com/wp-content/scripts/move-blogs.php
Shows that all the tables in the global database were created. I am able to connect to all the databases with the same user via MYSQL Workbench.

Here is the error:

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 database.

Are you sure it exists?
Yes they all exisit.

Does the user twbnet_bebold have permission to use the database?
Yes that user is able to use all the databases.

On some systems the name of your database is prefixed with your username, so it would be like username_. Could that be the problem?
Not the case here.

As it took this site down, I had to disable the multi-db for now. What is the issue here? I followed the instuctions exactly.

Thanks
