No one with the same error?

And this is the screenshot of the server. Every folder has 777 permission:

Thank you for your responds! But the HTML-Code is also wrong:

http://www.spassbibliothek.de/groups/fasching/

<div id="item-header-avatar">
	<a href="http://www.spassbibliothek.de/groups/fasching/" title="Fasching">

		<img src="" class="avatar" alt="Fasching">
	</a>
</div>

Any Idea? In which PHP-File is this located?
