    I have this code working all time but, after updating to WordPress 4.2.1, this doesn’t work.

    // return just the missing replies in the comment table
add_action( 'pre_get_comments', array( $this, 'return_missing_list' ) );
public function return_missing_list( $comments = array() ) {

    // bail on anything not admin
    if ( ! is_admin() )
        return;

    // only run this on the comments table
    $current_screen = get_current_screen();

    if( 'edit-comments' !== $current_screen->base )
        return;

    // check for query param
    if ( ! isset( $_GET['missing_reply'] ) )
        return;

    // now run action to show missing
    $comments->query_vars['meta_key']   = '_cnrt_missing';
    $comments->query_vars['meta_value'] = '1';
    $comments->query_vars['date_query'] = array(
                'after' => '10 months ago'
            );

    // Because at this point, the meta query has already been parsed,
    // we need to re-parse it to incorporate our changes
    $comments->meta_query->parse_query_vars( $comments->query_vars );
} // end missing_reply_list

    Can you help me about please?

    Thanks!

    Please try this.
    $comments->meta_query = new WP_Meta_Query();

    Before Doing
    $comments->meta_query->parse_query_vars( $comments->query_vars );

    Thanks Navnell.

    I don’t know why, but it applies the date filter but not the meta_key = meta_value .

    New syntax about meta queries?

    Any ideas?

    Why it applies the “date” filter but nothing about the meta_key & meta_value statement?.

    Thanks!

    Sorry I don’t have much information.

    I solved it using another type of code.

    add_filter('comments_clauses', array($this, 'return_missing_list') , 10, 2);
public function return_missing_list(array $pieces, WP_Comment_Query $query) {
		if (! is_admin())
		{ return $pieces; }
		// Esta función sólo se puede ejecutar si es admin
		$current_screen = get_current_screen();
		// bail on anything not admin
		if ( is_admin() && ('edit-comments' == $current_screen->base) && (isset($_GET['missing_reply'])))
		{
			global $wpdb;
			$pieces['join'] = " INNER JOIN wp_commentmeta ON ( wp_comments.comment_ID = wp_commentmeta.comment_id )";
			$pieces['where'] = "(comment_approved = '1') AND (comment_date >= DATE_SUB(NOW(), INTERVAL 1 MONTH)) AND (wp_commentmeta.meta_key = '_cnrt_missing') AND comment_type != 'pingback' AND comment_type != 'trackback'";
		}
	return $pieces;
	}

    Hope you find it useful.

    thanks! but altering the clauses may actually be a bad idea because it breaks caching. it doesn’t matter in your case but on frontend the comments query is cached using a unique key based on the query string. if you dynamically alter the clauses and use a persistant cache it returns the same cache for the same query string and possibly different clauses.

    i ended up using the comments_array which doesn’t break the cache but is not so ideal performance-wise. would be nice if pre_get_comments would work again as expected…

    No worries – it was messing in fairly critical ways with one of my plugins so I had to. FWIW, since 4.2.1 (and in the meantime) you can switch to using the parse_comment_query hook instead.

    ok, it seems that’s where the query alteration belongs. it doesn’t make sense anymore to use pre_get_comments for this…
