A feed could not be found

I’m getting “A feed could not be found” when I attempt to add my feed to my widgets. The URL of my site is: http://collegereadyaustin.com/news/

I’ve configured permalinks, and http://collegereadyaustin.com/news/feed/ comes up fine. It accepts it when I add this feed under Widgets (bottom widget on the left-hand side of the screen, titled EduUpdate). When it’s rendered on our site, it says:

RSS Error: A feed could not be found at http://collegereadyaustin.com/news/feed/

(actually, it’s cut off at “new” on the page, but view/source shows that it’s trying the full URL).

Any ideas?
