[quote author="flacznik" date="1369123851"]Then I think there might be something wrong with your configuration - check:

$route['default_controller'] = 'ci';

and

$config['base_url'] = 'http://localhost/ci/';

If you didn't place .htaccess in the root folder than you leave $config['index_page'] = 'index.php';[/quote]

of course there is no .htaccess in my ci directory!
directories are : application , system , user-guide
files : index.php
