Pon tu htaccess y podrias probar esta parte de la configuracion :
Código PHP:
Ver original/*
|--------------------------------------------------------------------------
| 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'] = "PATH_INFO";
$config['uri_protocol'] = "REQUEST_URI";
//$config['uri_protocol'] = "AUTO";
Prueba con cual te puede ir bien.
Saludos.
