I have created a MY_Controller Class that extends CI_COntroller inside the application/core folder.
Now what i want is to create another class that will extend the MY_Controller class but it is inside the application/libraries 
class Myclass extends MY_Controller
{
    public function index()
    {
     }
}
but when i load this class this is the result:
Unable to locate the specified class: Cache.php
Am I correct in saving Myclass.php inside the application/libraries ?
Is there any other way in extending CI_Controller ?
thank you sir newbie in codeigniter 3.0.0
                        
You're correct in extending MY_Controller in the application/libraries folder. However, you should create your MY_Controller extension of CI_Controller in the application/controllers folder.
