While one-to-many times you felt that the post revisions you have got in hand in your blog are very much useful BUT counting on another side, it is good to clear it up. To do so, simply paste the following snippet in your functions.php file and you are done.
1 2 3 4 | $wpdb->query( " DELETE FROM $wpdb->posts WHERE post_type = 'revision' " ); |
