3.0 not working! SHOCK!!!

3.0 not working! What a SHOCK!!!

Quick fix: I downloaded and installed 2.0.3

Deeper question: It statest I should use:

<?php echo("Hello, World!"); ?>

I have all code on separate pages. I typically use:

<?php $path = $_SERVER['DOCUMENT_ROOT']; $path .= "../../files/iphone4.php"; include($path); ?>

But even the “Hello, World!” does not show up.

I am not using Gutenberg, is that related?

(I am perfectly happy with 2.0.3 though)
