When looking at /includes/DefaultSettings.php and reading this: http://www.mediawiki.org/wiki/Manual:$wgRCMaxAge The default for $wgRCMaxAge is one week. Anything older than a week is deleted. If you look at the Special:RecentChanges page itself, ie: http://www.mediawiki.org/wiki/Special:RecentChanges You can filter by one week to 14 and 30 days. With an $wgRCMaxAge of one week the 14 and 30 day filters will never be valid, thus making users think the Special:RecentChanges page is buggy due to the inconsistancy. Changing this value is simplistic in itself but what's being packaged in the software should match with the page it's being used on.
This has already been changed to 13 weeks in 1.16.
