Thread:Extension talk:CategoryIntersection/is broken on Mediawiki 1.20.3

The extension fails on Mediwiki 1.20.3 with this messager in the apache errorlog: PHP Fatal error: Call to private method LinksUpdate::dumbTableUpdate from context '' in /www/docs/wiki/extensions/CategoryIntersection/CategoryIntersection.php on line 86,

Reason: the method LinksUpdate::dumbTableUpdate (from includes/LinksUpdate.php) is no longer public but private.
