The CategoryExplorer extension replicates the $wgUseCategoryBrowser configuration parameter that was removed in 1.38 for sites that want to continue using the functionality.

The feature was originally written by Antoine Musso in June 2004 in MediaWiki core with the intent was to ease browsing through parent categories similar to how it was done on DMOZ back in the days.

It may be useful on smaller wikis when there is just a few categories, making it easier to navigate / browse without having having to rely on hand crafted navigation box.

  • Add the following code at the bottom of your LocalSettings.php file:

  • Yes Done – Navigate to Special:Version on your wiki to verify that the extension is successfully installed.
