[support] db password change

I just tried changing the mysql user password for a live site. Changed the user's pw using cpanel and then on the settings.php file. The site reported back that it was offline even after several refreshes. I changed the user pw and settings.php file back to the old values and the site's up and running. What step did I miss here?
