After upgrading to MediaWiki 1.19.2, the skinning of EduClassics was not working for the wiki. It turns out that the fix is simple.
The following was added to the LocalSettings.php file
require_once(dirname(__FILE__) . '/../wp-load.php');
The following was added to the theme skin.
get_header( $name );
Next, adjustments were made to the CSS through the WP style sheet in the child theme.
The next mission is the WP Toolbar. I'm not sure how to add it to an external page but will tinker with it when there is time.
