CodeIgniter NGINX Rewrite Rules

[eluser]Cinghius[/eluser]
I apologize if I have not updated the post. Meanwhile, I paste a link that I found very useful:
http://wiki.nginx.org/Codeigniter
I solved the problem by simply changing,
from
$config['uri_protocol' = 'PATH_INFO';
to
$config['uri_protocol'] = 'REQUEST_URI';
