PHP-Pages in Subfolder with WP-Layout

Hi Folks!

I’ve got a little problem.
I want to put some content, which comes not from my wordpress-DB into the layout of my wordpress blog.
I have used for example php-script in a subfolder
mydomain.de/test/test.php

Until now I build the php-site like this:

<?php
require('../wp-blog-header.php');
?>
<?php get_header(); ?>
<div id="content" class="narrowcolumn">
<div class="post">
<h1>Testheadline</h1>
<div class="entrytext">
test-content
</div>
</div>
</div>
</div>
</div>
<?php get_sidebar(); ?>
<?php get_footer(); ?>

But this worked with WP1.5.2. It doesnt with WP202. Is there a way, which works in any case?

Regards!

Jens
