[SMARTY] Help Please-Compiled templates have headers only

Aloha,

Can someone please help. When I look into my compiled_templates folders the
files only have the compiled headers like so:

<?php /* Smarty version 2.6.9, created on 2005-07-24 09:41:31
         compiled from header.tpl */ ?>

None of my template is displayed. The same setup works fine in another vhost
on this machine. If I turn debug on then I see javascript when viewing the
page source.

Here¹s my php file:

define('SMARTY_DIR', '/usr/share/php/smarty/');
require_once(SMARTY_DIR . 'Smarty.class.php');
$tpl = new Smarty();
        $tpl->template_dir = '/home/httpd/vhosts/smithskauai.com/templates';
        $tpl->compile_dir =
'/home/httpd/vhosts/smithskauai.com/compiled_templates';
        
        $tpl->compile_check = true;
        $tpl->force_compile = true;
        $tpl->debugging = true;

$tpl->display('header.tpl');

Thanks for any help.
Gary
