Error in reading the variable from class.config.php

[GabrielUlici]

i think that the file class.database.php cannot read the variables set in class.config.php , in my case.
I set in the class.config.php for production

        $this->dbHost       = 'mysql17.000webhost.com';
        $this->dbName       = 'a5653879_shine';
        $this->dbUsername   = 'a5653879_jarvis1';
        $this->dbPassword   = 'password';
        $this->dbDieOnError = false;

but i receive an error " Warning: mysql_connect() [function.mysql-connect]: Access denied for user 'a5653879'@'localhost' (using password: NO) in /home/a5653879/public_html/Shine/includes/class.database.php on line 67"

then i changed in class.database.php this and it worked.

        $this->host       = 'mysql17.000webhost.com';
        $this->name       = 'a5653879_shine';
        $this->username   = 'a5653879_jarvis1';
        $this->password   = 'password';

Please tell me if i did something wrong.
Thanks.
