We are referencing the XML feed in Joomla... (we cannot use the coldfusion feeds)

Here is what we were using:

http://www.rcuniverse.com/rss/rss-mag-airplanes.xml

(as per the previous posts in this thread)

You can verify with your browser that the URL fails to retrieve the feeds and has the following error message (ie7):

"This feed contains code errors"

THANKS!
