Thread:Extension talk:RSS/Can't Find Version 2.X/reply

Please read the article page. As mentioned, you need r114168, because the recent reverts (for git migration) have reverted also the version numbers - of course.

In your RSS extensions directory use either svn up -r114168 or in your extensions folder use svn checkout -r 114168 http://svn.wikimedia.org/svnroot/mediawiki/trunk/extensions/RSS RSS for a fresh checkout of this older version.
