I’m not an auto-save hater. Got it turned on on my word processor. In fact, I insist on it. But having auto-save in WordPress and on the word processor are two different things. My biggest pet peeve, it increases my database size exponentially. Sure, web hosting space is cheap still, just because you have the space doesn’t mean you must fill it. Second reason, I’ve found sometimes the duplicates create weird issues. I can’t remember what happened the last time but the auto-saved version of the post completely messed up something.
I want it off and want it off now.
Here’s how. Just add the following code into your wp-config.php you can put it right after the list of security keys.
define('WP_POST_REVISIONS', false);
