I placed this bid to tell you more about your script is vulnerable, there is an error in your website can make any user read the config, check this:
$conf['database_name'] = "chesscoi_kinger";
$conf['database_login'] = "chesscoi_rooch99";
$conf['database_pass'] = "therock123";
This may lead to a full server breach and leak the information of your customers, if you like we can talk more about this.
