This will be really helpful to you, it was save my day too :)

in your config.php

Answer 2

In codeigniter 3 versions you can use files or database if files, make sure you have created folder where you would like your session path set and chmod 700

I use cache folder to store files sessions

$config['sess_driver'] = 'files';
$config['sess_cookie_name'] = 'ci_session';
$config['sess_expiration'] = 1440;
$config['sess_save_path'] = FCPATH . 'application/cache/sessions/';
$config['sess_match_ip'] = TRUE;
$config['sess_time_to_update'] = 300;
$config['sess_regenerate_destroy'] = TRUE;

Auto load session in application > config > autoload

$autoload['libraries'] = array('session');

Note: Make sure all file names and class names of controllers, models, libraries have first letter upper case example filename Welcome.php and class Welcome extends CI_Controller {}.

You also may need to have a encryption_key on config.php

$config['encryption_key'] = 'pXeQY2733rR560MrwJy40OL4WaSGmr5A';

Simply change this in your, application -> config -> config.php

$config['sess_save_path'] = NULL;

To

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

It will create a Directory in your Root. Hopefully your problem will solve ...

Thanks

Answer 4

This worked for me

$config['sess_driver'] = 'files';
$config['sess_cookie_name'] = 'ci_session';
$config['sess_expiration'] = 7200;
$config['sess_save_path'] = sys_get_temp_dir();
$config['sess_match_ip'] = TRUE;
$config['sess_time_to_update'] = 300;
$config['sess_regenerate_destroy'] = FALSE;

Answer 5

you can also put

output_buffering = On

in your php.ini file on the root

Answer 6

Change 'NULL' to either '/tmp' or your servers temp folder path

The line should now read:

$config['sess_save_path'] = '/tmp';

Answer 7

adding 'session' in autoload.php file solved my problem

$autoload['libraries'] = array('form_validation','session');

Answer 8

This work for me

$config['sess_save_path'] = sys_get_temp_dir();
