Posted on May 16, 2021 by ServerOk

On a web application, session not working.

$config['sess_expiration'] = 7200;
$config['sess_save_path'] = FCPATH.'ci_sessions';
$config['sess_match_ip'] = FALSE;
$config['sess_time_to_update'] = 300;
$config['sess_regenerate_destroy'] = FALSE;

$config['sess_driver'] = 'files';

$config['sess_cookie_name'] = 'ci_session';

$config['sess_expiration'] = 7200;

$config['sess_save_path'] = FCPATH.'ci_sessions';

$config['sess_match_ip'] = FALSE;

$config['sess_time_to_update'] = 300;

$config['sess_regenerate_destroy'] = FALSE;
