Oh... there's something wrong with the details (or constants) you specified in your dbConfig.php file. This is the code provided in the 1st page of this thread (with comments):
<?
// Replace the variable values below
// with your specific database information.
$host = "localhost";
$user = "UserName";
$pass = "Password";
$db = "dbName";
// This part sets up the connection to the
// database (so you don't need to reopen the connection
// again on the same page).
$ms = mysql_pconnect($host, $user, $pass);
if ( !$ms )
{
echo "Error connecting to database.\n";
}
// Then you need to make sure the database you want
// is selected.
mysql_select_db($db);
?>
The details in red are provided by your host. Most likely, you won't be changing
$host = "localhost"; but you need the
$user, $pass, and $db . Unfortunately, I can't get that for you since only you are supposed to know your password. The username ($user) and database name ($db) can be requested from your host.
You can't just guess values for that. Ask your host for those details. The script will work fine once you get those values.
Or if you use cpanel, I might be able to guide you into setting up a database.
