Unable to locate the specified class: Session.php [SOLVED]

Am integrating Facebook login using this library.
However after redirection from FB I get an error:

Unable to locate the specified class: Session.php

Other codes with 

PHP Code:

$this->session->set_userdata($str);
//and
echo $this->session->userdata('var'); 


seem to work elsewhere.

I think the problem is involved in this method but I can't find any problem.

Any suggestions?

Is this error generated by CI or Facebook?
It isn't formated like native CI errors (see attachment).

   

Did you loaded the session in autoload or in the construct function?

I did.


This is what the class that handles redirects from FB looks like

PHP Code:

<?php 

class Facebook extends CI_Controller
{
    public function __construct()
    {
        parent::__construct();
        $this->load->library('session');
    }

        /**
     * Callback to log with facebook account
     */
    public function login_callback()
    {
        if ($this->facebook->fb_callback()) {
            redirect('home');
        } else {
            show_error('erreur');
        }
    }
    
    /**
     * Callback to disconnect the facebook acount
     */
    public function disconnectFacebookAccount_callback()
    {
        $this->facebook->disconnectFacebookAccount();
        redirect('Welcome_fb_ion_auth');
    }
    
    /**
     * Callback to connect the user's facebook acount
     */
    public function register_callback()
    {
        $this->facebook->connectFacebookAccount();
        redirect('my-info');
    }
    

} 


I would autoload the session library because it is always used

./application/config/autoload.php

I would autoload the session library because it is always used

./application/config/autoload.php

it's autoloaded.
I only loaded it in the controller because I was curious uf something wasn't working properly.

Adding 

PHP Code:

$this->ci->load->library('Session'); 


to the library file, immediately after 

PHP Code:

$this->ci =& get_instance(); 


fixed the issue. This was suggested by someone at the Slack Chat 

Bad Luck.
The report from my last post worked when I copied my application to a new test folder.
Back to the real app and the problem persists.
So I removed sessions driver from the autoload.php, making thr file look like below

$autoload['language'] = array(); 


The I get the following error

Code:

An uncaught Exception was encountered
Type: Error

Message: Class 'CI_Ion_auth' not found

Filename: /home/indicxyz/airdata.com.ng/system/core/Common.php

Line Number: 196

Backtrace:

Well, the system is just appending CI_ to all my libraries before attampting to autoload them.
This does not happen on the test copy, even when the sessions driver is not autloaded!
Any suggestions?

Show the code were your setting up the $CI

Hi,
I copied the contents of the website to a new (test) folder and it worked from there.
So I deleted everything from the folder containing the original site, and copied contents of the test folder into the the original folder and it works. Quite weird.
