As mentioned I d check using phpAdmin that your logon credentials to your modX database is correct first. Once you are sure this is working ok then in modX the database configuration I believe is defined in the file

<site_home_directory>/manager/includes/config.inc.php

Right at the top it has this block which you should be able to edit accordingly.

<?php
/**
 *  MODx Configuration file
 */
$database_type =  mysql ;
$database_server =  localhost ;
$database_user =  db_username ;
$database_password =  mypassword ;
$database_connection_charset =  utf8 ;

Use mysql_connect function to connect to the database.

Also check to make sure that you are specifying correct credentials for the database connection.
