CI 3.1.11 session library location and load

I'm using the latest version of CI and I have problems to load the Session Class.
First I noticed that the class-file isn't in the 'standard location' (system/libraries) but instead in session/libraries/Session.
Second even if I try to load the library in the correct way with

PHP Code:

        $this->load->library('session/session'); 


in the head of my class definition AFTER parent::__construct();

I get the following error message(s):

Unable to load the requested class: Session

I'm pretty sure to have been overlooking something as I am actually shaken by a cold too.

Any help as always very appreciated!

3.1.11 is the latest in the 3.x branch, but the latest version is the brand new 4.0.2. I recommend using this version, because a lot have change since 3.x.

Anyway, to load the session library in 3.x, you just need to call $this->load->library(‘session’) as explained in the User guide.

If it's located in a different folder when /system/libraries/session you have a broken CI. Please download a fresh copy.

As per the documentation, you should load it like this. No library are loaded with a subfolder. https://codeigniter.com/user_guide/libra...-a-session

PHP Code:

$this->load->library('session'); 


I removed the 3.1.1 installation and replaced it by the 4.0 version.

Now, after I set it all up I get the following error message (in development more):

SYSTEMPATH/ThirdParty/Kint/init.php at line 46

Try to install with composer, I've done with that

Yeah I have done that...
Thanks.

Upgrading from CI 3 into CI 4 needs pretty much a complete rewrite of your application, it's not a drop in replacement.

Stick with CI 3, and solve the problem at hand.
