Support & Bugs

The only widgets that work are “Seo rankings” and "Visitors in real time. " Does anyone know what’s wrong? Plugins are enabled, I have flash 10.2, server installed php-gd (GD library), PHP version 5.2.14, MySQL version 5.0.91, Apache version 2.2.16, Linuw system.
My Piwik is here:
http://www.piwik.directorywebbsites.com/

Feedburner statistics widget gives me the message:

Warning: SimpleXMLElement::__construct() [simplexmlelement.–construct]: Entity: line 18: parser error : Opening and ending tag mismatch: meta line 2 and head in /home/director/public_html/Piwik/plugins/ExampleFeedburner/ExampleFeedburner.php on line 112
