How can I change the WordPress archive URL pattern?
Tonight I come to this question with no answer. Although it's quite late to answer, but I try to answer it for future reference.You can add following code snippet to functions.php file.
function change_archive_links() {global $wp_rewrite;// add 'archive'$wp_rewrite->date_structure ='blog/archive/%year%/%monthnum%/';}add_action('init','change_archive_links');Don't forget to flush WordPress rewrite rules after adding the snippet. To do that, go to WP Dashboard > Settings > Permalinks and press Save Changes button.
