รบกวนช่วยสอนวิธีติดตั้ง ckfinder php 2.1 ไฟล์ config.php error ครับ

function CheckAuthentication()
{
	// WARNING : DO NOT simply return "true". By doing so, you are allowing
	// "anyone" to upload and list the files in your server. You must implement
	// some kind of session validation here. Even something very simple as...

	// return isset($_SESSION['IsAuthorized']) && $_SESSION['IsAuthorized'];

	// ... where $_SESSION['IsAuthorized'] is set to "true" as soon as the
	// user logs in your system. To be able to use session variables don't
	// forget to add session_start() at the top of this file.

	return false;
}
