Limiting Revisions in WordPress

If you spend a lot of time revising a page or a post, you can build up quite a number of revisions in the database.

The following line in the wp-config.php file in the root of the site will limit the number of revisions saved to 5. You can use whatever number you want, within reason.

define('WP_POST_REVISIONS', 5);
