Thread:Project:Support desk/Validate RSS Feed

MediaWiki 1.16.0 PHP 5.2.15 (cgi-fcgi) MySQL 5.1.53-log

I'm attempting to make use of the rss feed on my wiki. Specifically, I want to display it on my related forum. However, I've tried running the feed through a Feed Validator and it keeps failing. Any ideas on what the issue might be? My wiki is only editable by registered users, but it is viewable by anyone.

This is the feed in question: http://markedrp.com/w/index.php?title=Special:RecentChanges&feed=rss

Any ideas?
