Hello Well the only thing I can see is that you need to fill out the database information. Here is what it looks like in your code:
Code:
// ****** MASTER DATABASE USERNAME & PASSWORD ******
// This is the username and password you use to access MySQL.
// These must be obtained through your webhost.
$config['MasterServer']['username'] = 'root';
$config['MasterServer']['password'] = '';
Just put in your database username and password there. Also make sure your Database name is correct. Do this and let me know if this works. If that does not/or does help let me know.
