Site Status: Turning off Post Revision Tracking
I discovered that WordPress was saving every revision of every post. So I turned off this feature by adding the following lines of code to the wp-config.php file for each of my blogs:
// Disable post revisions.
define(’WP_POST_REVISIONS’, false);
I also changed line 495 in the wp-settings.php file from
$default_constants = array( ‘WP_POST_REVISIONS’ => true );
to
$default_constants = array( ‘WP_POST_REVISIONS’ => false );
Then I deleted all the revisions that had been saved to this point from each blog database by executing the following SQL statement:
DELETE FROM wp_posts WHERE post_type = ‘revision’;
I then logged out and back into each site’s admin id and verified that the revisions saved thus far no longer appear on the Edit Post screen. The deletion apparently worked.
That’s all.
