[SOLVED] My_Controller ?

[eluser]solid9[/eluser]
I tried calling it in the URL like this below,

Code:

http://thefml.org.uk/secret/MY_Primary/index/

Is that the right way to call it in the URL?

If yes, then I have error below,

Code:

Message: Cannot modify header information - headers already sent by (output started at /home/struhi/public_html/thefml.org.uk/secret/application/controllers/MY_Primary.php:19)
