Call

Code:

parent::__construct()

Since CI 2.x there is no more Controller but a CI_Controller class. That's why it does not work for you.

Secondly, please use [ code ] tags (without the spaces) if you want to post code.

Post the whole controller, not just the constructor. Is your class extending CI_Controller or just Controller? I'm guessing you're extending Controller since that's how you originally had the construct.

First things first: Keep consistency with CI naming conventions, i.e., it's always

CI_Controller

meaning C, I, and C (of Controller) are capitalized.

Secondly, controller classes also need to be capitalized, i.e., in your case Site.

These things should, in the short run, solve your problem.

It says exactly what line the error is on. You're calling a method that doesn't exist. If you don't understand that, you should take some time to learn more about PHP and object orientated programming.
