The Unicon News portlet is configured to consume this RSS feed:
Unfortunately, that path no longer points at an RSS feed of news, instead rendering a web page.
Apparently this is the new RSS feed: http://www.unicon.net/about/news/feed
Jasig could remove this error in future releases by switching to this new feed. However, I've also opened Unicon-internal defect report "WEB-499" to internally track the request to get the expected RSS feed back up.
Corrected priority of defect.
