Some time ago Lorenzo Breda had some trouble with RSS. I run into the same problem with "An error occurred while fetching this feed: "
The latest release of DokuWiki includes a version of SimplePie (the RSS parser) that needs the php extensions "Multibyte string extension" OR "iconv". These are not included by default in php version 4.4.7
More info about this at http://simplepie.org/wiki/setup/requirements
