After a little googling, I found adding changing $config['sess_save_path'] from NULL to sys_get_temp_dir(); in config.php fixed the problem. Reading up on this led me to https://www.codeigniter.com/user_guide/l...sions.html and there it was suggested I load $this->load->library('session'); after parent::__construct() in MY_Controller. Trying this (after setting $config['sess_save_path'] back to NULL) gave me an error again, so I'm back to the sys_get_temp_dir(); as the value to $config['sess_save_path'].

So my question is, is this a usual thing when setting up the live app environment, or should I be concerned about something at this stage? As a noob, it's quite hard to ask questions about something I am new to, but I'm just trying to make sure I'm not going too far off track here while trying to understand as much as possible.

Thanks.

Why did you ignore this note?

You're not supposed to leave it empty.
And you are again NOT supposed to set it it to sys_get_temp_dir(), especially if you're uploading to a shared hosting environment.

Just pick a directory that only you can read, and point to it.

what i finally did to overcome this, is:

the prod installation has in index.php:

define('ENVIRONMENT', isset($_SERVER['CI_ENV']) ? $_SERVER['CI_ENV'] : 'production');

while the installation on my dev PC has:

define('ENVIRONMENT', isset($_SERVER['CI_ENV']) ? $_SERVER['CI_ENV'] : 'development');

so, remove completely the line about sess_path line from the application/config.php file and define the path (use absolute path, i could see the absolute path in the log, i dont see it in your case, you will have to discover it somehow, maybe even ask the server admin) on each file (config/production/config.php and config/development/config.php), and by changing the ENVIRONMENT in the index.php, you can make CI load the path you need per system. before all that, i had relevant path (../xxx/xxx/session_path for example), but when i migrated to the hosting server, i ended up in the above trouble and had to switch to absolute paths.

hope it helps

This has nothing to do with the OP's question and you're giving a very bad advice.
