It’s a simple sidebar widget that displays your twitter updates.
The widget is not updated to support PHP 4 by using the PHP XML parser instead of the SimpleXML extension.
Cheers!
Check back often. I’ll update the widget when I have time.
The problem is that you don’t have the SimpleXML extension enabled. It requires at least PHP 5.0 and is on by default. If a number of people would like it, I’ll rewrite it using the DOM XML extension to support older versions of PHP.
I guess I phrased my statement a little ambiguously. Instead of having <script type="text/javascript">, the plugin uses <script class="javascript"> which does not validate.
