MediaWiki 1.23 deprecates the skin autodiscovery mechanism of core skin files. After upgrading to this version, you should ensure that the old files $chick, $nostalgia, $simple and $standard directly in the $dir directory as well as the according subfolders inside the $dir2 directory got removed. MediaWiki will log warnings if any of them are still found to help you remember. (You will also need to adjust any custom skins to follow a similar convention.) See $discovery for details.
