Now I know a similar question has been asked before, but please bear with me. So I'm using the same line of code on two seperate pages yet one displays  and the other doesn't. What would be causing this?
The below code is on each of the two before mentioned pages:
<?php include("footerblock.php"); ?>
Which refers it to this code here:
<?php session_start(); ?>
<html><head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8"/>
</head><body>
<table style="text-align: center; width: 100%;" border="0" cellpadding="0" cellspacing="0">
<tbody><tr><td style="text-align: center;">
<?php
$cmtx_identifier = 'cmtx_reference';
$cmtx_reference = 'cmtx_url';
$cmtx_path = 'comments/';
require $cmtx_path . 'includes/commentics.php'; //don't edit this line
?>
</td>
</tr></tbody></table></body></html>
