Joomla Error loading feed data

The error occurs after installing joomla.

So fix the thing all you need to do is:
1. go to administrator panels
2. Extensions -> Module Manager -> Administrator tab
3. Find "Joomla! Security Newsfeed"
4. Disable it
5. Done

If you have the “yoo_tweet module” installed, disable this module as well.  This module is known to display this error message.

Why:

Because this module load feed data with link http://feeds.joomla.org/JoomlaSecurityNews, this link is broken, so it pop up a error loading feed data error.

Have fun!
