I've fumbled around with a bit and only managed to get more errors than what I've started out with.</p> <p>possible help?</p> <p>This is what I have to change/add - somehow<br /> <pre><code>Valid XHTML If you&#39;re using XHTML, the custom attributes will not pass validation. To make your XHTML technically valid, you&#39;ll need to add a custom namspace declaration to your opening &lt;html&gt; tag. (Note that the W3C validator does not take custom namespaces into account.) Change &lt;html xmlns=&quot;http://www.w3.org/1999/xhtml&quot;&gt; to &lt;html xmlns=&quot;http://www.w3.org/1999/xhtml&quot; xmlns:addthis=&quot;http://www.addthis.com/help/api-spec&quot;&gt;</code></pre>
