Cannot connect to database

[phatPhrog]

We have a new server and Sitebuilder was supposedly pre-installed, yet each time we attempt to go to the site either through URL or Plesk C.P. button, we get

Cannot connect to database

and therefore not allowed to configure it.

Where is the config file?
Can we manually edit it to make it work?

So many questions and no answers.

Thanks to any that can help.

Database configuration is defined here:

/usr/local/sitebuilder/include/config.php
