Added a new template file to a theme – get Call to undefined function error

I added a new file in the theme folder and it doesn’t seem to be working properly.

The first line get_header(); creates an error Fatal error: Call to undefined function get_header() like it’s not seeing any includes.

Any ideas why that happens? All files in the same theme folder work just fine except this one.

You are prbebaly using wordpress elements outside the loop
and since its a file ou dont access directly from wordpress
structure but a file you created yourself you should include

<?php
require_once("../../../wp-load.php");
?>
