title: Debugging CodeIgniters 404 errors
body: <p>I'm having a nightmare uploading my site to the production server. The site runs fine locally and on a staging server (exactly the same server, settings as the production site). However when I deploy to production I'm getting a 404 error from CI.</p>
  
  <p>CodeIgniters 404 error pages are frustrating because it seems as if i can't access other libraries from them. How can I go about debugging the error? See which controller is trying to be called etc.</p>
