Looks like subpages aren't enabled on the template namespace. The wikipedia template apparently uses relative template references, so subpages need to be enabled in that namespace for that to work.

Add the following to the bottom of LocalSettings.php: $wgNamespacesWithSubpages[NS_TEMPLATE] = true;

See manual:$wgNamespacesWithSubpages for details on what that does.
