See below for settings in autoload.php and config.php. Let me know if I incorrectly configured them. Also, why do you say session library "sometimes active, and sometimes not"?
Code:
/*** autoload.php **/
$autoload['libraries'] = array('database', 'session','form_validation');
/*** config.php ***/
$config['sess_cookie_name'] = 'ci_session';
$config['sess_expiration'] = 14400;
$config['sess_encrypt_cookie'] = TRUE;
$config['sess_use_database'] = TRUE;
$config['sess_table_name'] = 'ci_sessions';
$config['sess_match_ip'] = FALSE;
$config['sess_match_useragent'] = TRUE;
$config['sess_time_to_update'] = 14400;
$config['cookie_prefix'] = "mydomain";
$config['cookie_domain'] = "";
$config['cookie_path'] = "/";
....
$config['time_reference'] = 'local';
