I'm trying to use CodeIgniter with Nginx. I'm on development so I'm running on localhost. This is my /etc/nginx/sites-avaiable/default file:
# You may add here your # server { # ... # } # statements for each of your virtual hosts to this file ## # You should look at the following URL's in order to grasp a solid understanding # of Nginx configuration files in order to fully unleash the power of Nginx. # http://wiki.nginx.org/Pitfalls # http://wiki.nginx.org/QuickStart # http://wiki.nginx.org/Configuration # # Generally, you will want to move this file somewhere, and start with a clean # file but keep this around for reference.

* Maps to the following URL * http://example.com/index.php/welcome * - or - * http://example.com/index.php/welcome/index but Nginx still throws a 404 error. I originally posted this question on StackOverflow: https://stackoverflow.com/questions/31932160/php-codeigniter-nginx-throws-404-and-ignores-class-and-method
but I noticed that the solution to a similar problem was found on ServerFault: Codeigniter in subdirectory on Nginx 404
so I decided to post this here as well. Thanks in advance for any help.
