WordPress will trim revisions on a post when creating new revisions, this is how it does it at the end of wp_save_post_revision: // If a limit for the number of revisions to keep has been set, // delete the oldest ones. $revisions_to_keep = wp_revisions_to_keep( $post ); if ( $revisions_to_keep < 0 ) { return $return; … Read more
How is revision works internally?
By default WordPress can display changes in post content, by using the post revisions feature. WordPress can however not by default show any changes in post status (or publish date, or author, etc.). However there are plugins that can solve this. I built one myself called Simple History that displays more information about the changes … Read more
is there a way to see all changes been done on a wordpress site?

Please take database backup and run a below MYSQL query and check is this helpful: DELETE FROM wp_posts WHERE post_type = “revision” AND ID NOT IN(SELECT ID FROM wp_posts WHERE post_type=”revision” ORDER BY ID DESC LIMIT 5)
It’s not a good idea to run old versions of WordPress. Fortunately, you can quite easily turn off post revisions by using the wp_revisions_to_keep filter.

This had to do with the user not having the CPT capabilities access set up properly.

The problem turned out to be the transition from utf8 encoded databases to utf8mb4. Apparently the editor was getting a silent error and defaulted to dropping the transaction. The Solution: Recently WordPress has started switching to using utf-8mb4, so most people probably need to change their charset <meta charset=”UTF-8″ to <meta charset=”UTF-8mb4″>. Very old and … Read more
I think that revisions are disabled by default in the latest WP (but can’t guarantee that). I do know that if you want to enable revisions, then change an value in the wp-config.php file: define( ‘WP_POST_REVISIONS’, 3 ); That will save the last 3 revisions. Turn if off with a value of 0 or false. … Read more
