error 404 not found.

Hi
it's possible to make the codeigniter compatible with nginx and vestacp?
i've an problem with this, and most of the users had seen this:
error 404 not found.
soo, i would like to tell directly to the developers and coders that it would be an great help if this framework had support for this platform, because we can't modify the files from the website config widout making an huge mess to all the websites.

Thank
