[xwiki-users] Still have a problem with the RSS feed ...

I asked how to set up the RSS feed the other day and was quickly pointed to Anca Luca's answer ( http://lists.xwiki.org/pipermail/users/2010-January/018932.html), which I was able to implement. The RSS feed did work ... on that day, but not any more ... ? Can anyone help me? Thanks, Xavier
