Ok, I'm trying to display a PHP file inside a div in another PHP file.

I'm using the following code to do this,

<?php include('myfile.php'); ?>

I know that code is right, but for some reason it's just not displaying...

Any thoughts?
...I have also tried

<?php include("myfile.php"); ?>

No, it is set to OFF

(I guess that is the reason then)

How do I change this?
