You will have to delete revisions in the database; there is, strangely, no current provision from WordPress.
i.e. Delete from wp_posts where post_status=’revision’ and ….
You can restrict the number of revisions by adding
define (‘WP_POST_REVISIONS’, X);
to wp-config (where X is the number of desired revisions, default=until your database falls over with the burden).
Greaty, I was just looking for this too 🙂
So presumably you could add X = 1 to just save one revision, i.e. the current post ?
That’s great for those that have a clue how to do this and no problem messing with back end config … but I’m not one of those. I want these gone and an easier way to do it … come on WordPress … this is a space waster for those of us with small blogs. How above a way to delete them once the post has published?
@jo5329: adding define (‘WP_POST_REVISIONS’, X); seems pretty darn simple to me since you need to add other things to that file anyway when setting up WP 😉
Though I agree it would be much better to have it in the control panel — maybe in the Settings/Writing admin area.
I think this functionality will come in due time. In the meantime, I’ve been using the WP-CMS Post Control plugin over at http://wordpress.org/extend/plugins/wp-cms-post-control/ to disable post revisions. It also allows you to control over aspect of the write post/page panel, and turn off autosave.
