Fatal error: Call to undefined method Title::newfromrow() in C:\WOS\www\mediawiki\extensions\CategoryTree\CategoryTreeFunctions.php on line 479 Appears on my fresh MediaWiki homepage when {{#categorytree:All_categories|mode=pages}} when All_categories is the root category and there is at least one subcategory. Error does not occur when building category tree from any of the subcategories.
I assume this is a version mismatch issue. The latest version of CategoryTree requires the *latest* version of MediaWiki, i.e. current 1.13alpha from svn (developer's version, not a release!) So, if you are running MediaWiki 1.12 (latest stable), select 1.12.x on http://www.mediawiki.org/wiki/Special:ExtensionDistributor/CategoryTree to get a version of CategoryTree that works with your installation. I'll close this for now, feel free to reopen it if the problem persists when using compatible versions of MediaWiki and CategoryTree.
