WordPress tip: Close trackbacks on all posts at once

Simply run the following SQL query on your WordPress database, using the command line client or PhpMyAdmin. This will close pingbacks/trackbacks on all existing posts.
Don’t forget to backup your database before using this query.

UPDATE wp_posts SET ping_status = 'closed';
