But if there is only one author of WordPress blog, Post Revisions will taking too much space as every revision is a new row in wp_post table. It creates a alot of useless database-entries.
To disable Post Revisions, Add:
define('WP_POST_REVISIONS', false);
into wp-config.php, the wordpress 2.6 Post Revisions now disabled.
In my little opinion, there should be an option in general or writing settings to enable/disable the post revision feature.
You might also want to disable autosave, which also creates an extra row in the table when editing an existing post.
ReplyDeletedefine('AUTOSAVE_INTERVAL', 600000)
sets the interval to a very long period, so you won't ever get an auto save.
