Using 'More' tag on a Static Page – problem

Hi,

I’m trying to enable using a the ‘more’ tag in a static page. I’ve read this can be an issue (as I’ve found it to be), and encountered some sites suggesting I add the following code to the ‘loop’:

<?php
global $more;
$more = 0;
?>
//The code must be inserted ahead of the call the_content, but AFTER the_post()

<?php the_content('Continue Reading'); ?>

There is no ‘loop.php’ in my theme (it’s a child theme of superhero), but I think I’m supposed to use ‘index.php’ instead. Is that right?

If so, at what point do I insert the code?

Thanks in advance.
