h1-Tag is not working after moving servers

Hi there,

after moving my wordpress to a new server, my self-build h1-Tag is not working anymore.

<div id="header">
<h1><a href="<?php bloginfo('url'); ?>"><?php bloginfo('name'); ?></a></h1>
<? if (is_page(3)) { ?>
<p><strong><? bloginfo('description'); ?> f&uuml;r deine Party</strong></p>
<? } else {?>
<p><strong><?php wp_title(''); echo ' - '; bloginfo('description'); ?></strong></p>
<? } ?>
</div>

What should it do?

– When it is the startpage (id 3): Just show the Desciption (“Hits und Charts”) of the blog followed by “für deine n?chste Party”. One line.
– Every other page should take the title of the page, followed by “-” and the Discription (“Hits and Charts”). One line.

What is going wrong?

Can someone help to fix?

Thanks so much!
David
