Solution:

Have you tried to print session by print_r($_SESSION) on your view page. Print it, if your session is set it will show you.

Solution:

Use database session

https://codeigniter.com/userguide3/libraries/sessions.html

$config['sess_driver'] = 'database';
$config['sess_cookie_name'] = 'ci_session';
$config['sess_expiration'] = 7200;
$config['sess_save_path'] = 'ci_sessions';
$config['sess_match_ip'] = FALSE;
$config['sess_time_to_update'] = 300;
$config['sess_regenerate_destroy'] = FALSE;

Thanks.

Solution:

$config['sess_driver'] = 'files';
$config['sess_save_path'] = '/var/www/html/my_app/tmp/';

From codeigniter documentation:

'sess_save_path' | | The location to save sessions to, driver dependent. | | For the 'files' driver, it's a path to a writable directory. | WARNING: Only absolute paths are supported! | | For the 'database' driver, it's a table name. | Please read up the manual for the format with other session drivers. | | IMPORTANT: You are REQUIRED to set a valid save path!

If you dont want to change that folder manually every time when you change server, you could try something like

$config['sess_save_path'] = FCPATH . 'tmp/';
$config['sess_save_path'] = BASEPATH . 'tmp/';

The fcpath one should be xxx/my_app/tmp and basepath should be xxx/my_app/application/tmp

Both folders should be writeable.
