RSS Error

Hi,

I have enabled the RSS Feed icon to be shown in category listing, however, when I click on the icon, I got the following error:

Fatal error: Class 'JFeedItem' not found in /xxxxx/xxxxxx/public_html/xxxxxx/components/com_communitypolls/views/polls/view.feed.php on line 77

This can be tested live on the page http://www.golfads.info/polls.html

Thanks
