My Site RSS is Empty

I have a website: www.smartsailing.org/tr . But my site's feed is empty. I couldn't fixed that problem. You can see on this link www.smartsailing.org/tr/?format=feed&type=rss
How can I fixed it?

1. Unlikely it is related to Mobile Joomla.
2. As far as I know, your rss link is link to homepage feed (usually feed of featured items), and either you don't have featured items, or your hamepage is not featured blog view of com_content component.
