WordPress is a content management system, and the content is sacred. Every change you make to every page, every post, is tracked in a revision system, just like the Wikipedia. This means if you make a mistake, you can always undo it. It also means if you’re trying to figure out why something is on a page, you can see precisely the history and edits that led to it. These revisions are stored in our database.
This is very important, it’s at the core of the user promise of protecting your data, and it’s why WordPress is architected and designed to never lose anything.
WP Engine turns this off. They disable revisions because it costs them more money to store the history of the changes in the database, and they don’t want to spend that to protect your content. It strikes to the very heart of what WordPress does, and they shatter it, the integrity of your content. If you make a mistake, you have no way to get your content back, breaking the core promise of what WordPress does, which is manage and protect your content.
