Question

I am using

Apache/2.2.16 (Debian)

PHP Version 5.3.3-7+squeeze13

and for main idea for problem see below

my problem is same as define here Extended Controller class not found – stumped!

Then I proceeded to extend the controller class with only a
constructor to keep it simple:

<?php


class MY_Controller extends CI_Controller
{
    public function __construct()
    {
        parent::__construct();
    }
}
?> 

Then in the ‘application/controllers/welcome.php’ controller I changed
the name of the “Controller” class it extends to my new extended class
“MY_Controller”

<?php

class Welcome extends MY_Controller
{
    public function Welcome()
    {
        parent::__construct();    
    }

    public function index()
    {
        $this->load->view('welcome_message');
    }
}

Then I run the site and I get

Fatal error: Class ‘MY_Controller’ not found in
/application/controllers/welcome.php
on line 4

this error only showing on live server, it is working fine on localhost and also working on Apache/2.2.22 (Ubuntu) but not on Apache/2.2.16 (Debian).

i also tried change parent::__construct(); with parent::Controller(); but same error.

any solution thanks

Answer 1

put class MY_Controller (as MY_Controller file) in application/core folder (CI version 2.0 or higher)
With lower version, put in application/libraries
