[SOLVED] My_Controller ?

[eluser]solid9[/eluser]
This is what I did so far,

Code:

class My_mother extends CI_Controller
{
  function __construct()
  {
   parent::__construct();

  }
  
  function index()
  {
   echo 'Mother ship';
  }
}

And I name the file mother.php

But it show some error and the error is,

Code:

Message: Cannot modify header information - headers already sent by (output started at /home/struhi/public_html/thefml.org.uk/secret/application/controllers/mother.php:13)
