Making fonts awesome work ?

I've been struggling with fa fa icons not showing up. Then I found this solution on SO and it worked:

That's in config.php, I used to have $config['base_url'] = 'http://www.mysite.ca' Then I changed it to:

Code:

$root=(isset($_SERVER['HTTPS']) ? "https://" : "http://").$_SERVER['HTTP_HOST'];
$root.= str_replace(basename($_SERVER['SCRIPT_NAME']), '', $_SERVER['SCRIPT_NAME']);
$config['base_url'] = $root;

Is this a standard way to make fonts awesome work or there is a simpler way? And why it worked when I changed it?

Just set your base url to your site root url that also works.

Code:

$config['base_url'] = 'http://localhost/ci';
