using base_url in errors/error_404.php

Thanks ur suggestion worked great.

From what I have understood with all the trial and error methods and also from the answer of vrencianz, the error pages have an instance of CI_Controller only if show_404 is called from within a Controller. With this instance one could achieve as described on the answer of vrencianz.

But in cases where the error pages are called implicitly without an instance of the controller (For example: when a controller is not found), the CI_Controller instance is not found in this case and therefore base_url would not work.

So the wisest solution would be to use the $_SERVER['SERVER_NAME'] instead of base_url in the error pages.

Thanks marcogmonteiro and vrencianz for the help in helping me understand how it actually works.
