requested URL was not found on this server

[eluser]omidrs[/eluser]
So this is the section from the config.php file

/*
|--------------------------------------------------------------------------
| URI PROTOCOL
|--------------------------------------------------------------------------
|
| This item determines which server global should be used to retrieve the
| URI string. The default setting of "AUTO" works for most servers.
| If your links do not seem to work, try one of the other delicious flavors:
|
| 'AUTO' Default - auto detects
| 'PATH_INFO' Uses the PATH_INFO
| 'QUERY_STRING' Uses the QUERY_STRING
| 'REQUEST_URI' Uses the REQUEST_URI
| 'ORIG_PATH_INFO' Uses the ORIG_PATH_INFO
|
*/
$config['uri_protocol'] = "AUTO";


This was my initial setup -> having it as AUTO

I tried each one of the other ones individually and no luck.
I mean if you have any idea of what is causing the problem, or why codeigniter is giving me the page 404, i would very much like to hear it.
cuz www.example.com/index.php gives me my home page and if any of the other pages are setup to be the default_controller they all work but, www.example.com/index.php/anything does not work. when i type it in the url or i click on any of my links

thanx in advance for the help u guys are offering
Thanx a bunch
