You need to play around with your config/config.php file

these areas to be exact:

Code:

/*
|--------------------------------------------------------------------------
| Index File
|--------------------------------------------------------------------------
|
| Typically this will be your index.php file, unless you've renamed it to
| something else. If you are using mod_rewrite to remove the page set this
| variable so that it is blank.
|
*/
$config['index_page'] = "index.php?"; // try adding a "?"

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";
