Thread:Extension talk:AJAXPoll/Fatal error: Call to protected method Parser::addTrackingCategory()

Using Mediawiki 1.17, I get the following error when I try to save a page with a poll. Any help would be appreciated.

Fatal error: Call to protected method Parser::addTrackingCategory from context 'AJAXPoll' in /home/phusewik/public_html/test1/extensions/AJAXPoll/AJAXPoll_body.php on line 36

Thanks in Advance
