Opencart Quick Install No Formatting (Not loading CSS)

I found the problem. Google chrome was blocking mixed content.

In config.php the line:

// HTTPS
define('HTTPS_SERVER', 'http://yourdomain.com/');

needs to be changed to:

// HTTPS
define('HTTPS_SERVER', 'https://yourdomain.com/');

Is this an install script bug and if so do you want me to create an issue on GitHub? @eris @Raphael
