Controllers not loading views

[eluser]ssharp[/eluser]
I have three controllers in my app. Two of them will not load views and the other will. It's not an issue with the actual view files, because the controller that does work will load the views associated with the other two controllers. The two controllers that don't work will not load any view at all.

Note that everything worked fine until I put the files on a new server. I think the config is okay but I'm not sure why CI is behaving this way.

The the controllers that aren't working produce 404 Pages.

Any ideas? This is driving me crazy!
