More verbose error handling?

[eluser]kylemac[/eluser]
I am working on migrating my application from my local machine to my new VPS. The application works like a dream locally, but on my server I get a persistent 404 error.

My first question is how do I get my errors to be a little more verbose, so that I can track the issue? Is this possible?

Secondly, is this a familiar issue? I have tested this in both apache and nginx, and I get the same 404 error for both.
