[quote author="mejlo" date="1297040342"]Hi,
move application/libraries/MY_Controller.php to application/core/MY_Controller.php
When you extend core class, you must put it in "core" directory[/quote]

I've done what you said, but I get this error message:



A PHP Error was encountered

Severity: Notice

Message: Undefined property: Welcome::$load

Filename: controllers/welcome.php

Line Number: 12


Line 12 is:
$this->load->view('welcome_message');
