  • Hi,

    If you are looking for a temporary solution until the update, here:

     

    functions.php

    add:

    /**
     * Tests if any of a post's assigned categories are descendants of target categories
     *
     * @param int|array $cats The target categories. Integer ID or array of integer IDs
     * @param int|object $_post The post. Omit to test the current post in the Loop or main query
     * @return bool True if at least 1 of the post's categories is a descendant of any of the target categories
     * @see get_term_by() You can get a category by name or slug, then pass ID to this function
     * @uses get_term_children() Passes $cats
     * @uses in_category() Passes $_post (can be empty)
     * @version 2.7
     * @link http://codex.wordpress.org/Function_Reference/in_category#Testing_if_a_post_is_in_a_descendant_category
     */
    if ( ! function_exists( 'post_is_in_descendant_category' ) ) {
        function post_is_in_descendant_category( $cats, $_post = null ) {
            foreach ( (array) $cats as $cat ) {
                // get_term_children() accepts integer ID only
                $descendants = get_term_children( (int) $cat, 'category' );
                if ( $descendants && in_category( $descendants, $_post ) )
                    return true;
            }
            return false;
        }
    }
