RSS Feeds not working.
 

I have a network of 5 sites, so i created a subforum called "arquinetWORK feeds" to create a post, everytime i add a new entry on my other sites (all of them are on wordpress)

The subforum where the feeds are created has the option to add new threads, and i have added the four feeds in the admin panel. But none of the feeds creates a new thread.

This is how i setup the feed, and the feed points to
http://www.arquitour.com/feed/


Also when going to "feed preview" i recive the following:


So what am i doing wrong, since no new thread is created in the subforum, and im adding a lot of new entries at the four sites?

Thanks for your help :D
