Hello to everyone,

I really need some help here after upgrading both php and codeigniter to the last version Im getting all this warnings related to session:

Here is the problematic class:

<?php
defined('BASEPATH') OR exit('No direct script access allowed');

class MY_Controller extends CI_Controller
{
   
public $data = array(

'title'=>'AssociationFx',


);

   
    function __construct()
    {
        parent::__construct();
       
      $this->load->helper('MY_helper');   

        if(isset($_SESSION['logged_in'])){
        $this->data['logged_in'] = $_SESSION['logged_in'];
        $this->data['firstname'] = $_SESSION['firstname'];
        $this->data['id']        = $_SESSION['id'];
        $this->data['permission']= $_SESSION['permission'];
        }
     

    }
}

What version of CI did you have before upgrading? And what version did you install? It looks like you are using 3.x, not 4.0.2.

And the problem seems to be that your MY_helper file is changing the session parameters while the session is already started.

You are rigth, I was mistaking, Im running 3.1.10. I use to have 2.2.6 
As for the helper the problem dosent seams to come from there because if I comment out the line nothing change.
What else could be?

You need to replace the whole system folder, Sessions are now in a folder of there own.

you also need to replace the application config.php file it has a lot of changes.

Please make backup of these files just in case of an error.

What did you Try? What did you Get? What did you Expect?

If you made some change and still have errors, copy those new errors here. And put that in a “code” block. It’s easier to read.
