You may need to change the URI protocol thats used for your server setup

Code:

/*
|--------------------------------------------------------------------------
| 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";

change the "AUTO" to PATH_INFO and see if that helps if not try the others, thats how i fixed my problem with the 404 page
