Hello I'm new to codeigniter and I have just a simple code here
blog.php:

Code:

<?php
class Blog extends Controller{

    function index()
    {
        echo "Test!";
    }

}
?>

I use xampp as "home server" and I just get a white page when I running this... Please Need help.. I think this is because of the xampp because it's working with wamp server at another place
