[TYPO3-english] tt_news RSS feed empty

[nomen nescio]

Hi all,

I am trying to setup the RSS feed for plugin tt_news. I followed these 
instructions 
(http://typo3.org/documentation/document-library/extension-manuals/tt_news/2.5.0/view/1/7/#id2939753), 
setting up the template, but despite the feed is generated (title, 
description etc.), no news is shown there. TS is the same of the typo3 
guide.

Any idea about how to solve this problem?

Thanks in advance,
C.
