News article pages 404

Double segments show up in your browser's location bar because you clicked a link that sent you to that location. If you fix how the link is being generated, you'll fix the double segment showing up.

Your routes could be an issue if you didn't put them in the right place. I can't see your whole application, but they should be in application/config/routes.php (there's already a file there waiting for you).

The code in your controller's view() method can also throw a 404 error using show_404() if it can't find a news item. Make sure that that isn't what's creating the 404 error, also.
