Fresh installation CI 2.0 - error at startup : 404 Page Not Found with REQUEST_URI

[eluser]bgougent[/eluser]
In my previous version I needed to use

Code:

$config['uri_protocol']    = 'REQUEST_URI';

on my server.
When I try this on CI 2 it is not working and gives me a 404.
The other settings does not give a good result (like in CI 1.7.x) when I want to go to an other controller.

Please some advice...
