[RESOLVED WORKSFORME] Can't Find Version 2.X
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.
Ok, still working on this. Seems like the documentation has some things labeled wrong. All 3 code segments say they are for Mediawiki:Rss-item, but I think the last two are supposed to be Mediawiki:Rss-feed? Also it later mentions Template:RSSPost, but I think that has been replaced by Mediawiki:Rss-feed in the newest version? --FlyingRagnar (talk) 15:04, 28 March 2012 (UTC)
The documentation refers to the latest version.
I took over to maintain the extension some months ago, also because I use it in my wikis, but I was and I am still unhappy with the message text names and the handling of it.
The documentation refers to latest version but this mediawiki.org still uses the old version, which makes it complicated.
I suggest you use the extension "out of the box" - this will guarantee you have the correct message templates.
