I got a strange problem with RSS feeds on my blog: some news-reader (like Mozilla Thunderbird) gives an error saying that mine is not a valid rss feed! Other software (like FeedReader) seems to read it without broblems.
The strange thing is that all other blogs i've seen based on WP 1.5.2 like mine, output feeds perfectly working with any software, and the code of those feeds is absolutely identic to mine in their syntax and structure (of course...).
So the question is: why only my feed gives an error???
My feed is here: http://zeligplanet.altervista.org/feed/
Thanks if someone can help me! :-)
