[Mediawiki-l] RSS-Feeds not valid?

[Katharina Wolkwitz]

Hi all,

when I try to subscribe (in thunderbird) to an rss-feed to the 
recent-changes-page or the new-pages-page in my wiki, I get an error-message 
that 
http://wiki-h00.fhb.fh-swf.de/_fhbwiki/index.php?title=Spezial:Neue_Seiten&feed=rss
"ist kein gültiger rss-feed" (the rss-feed is not valid) and when I put the URL 
into the http://feedvalidator.org I get "It looks like this is a web page, not a 
feed. I looked for a feed associated with this page, but couldn't find one. 
Please enter the address of your feed to validate."

Strangely I can subscribe to the feed via Firefox and the sage-extension without 
problem.
But as I really need to use Thunderbird to view it, I need help...

Regards
Katharina
