All of you might know WordPress has a trash feature, just like Recycle bin in Windows PC, so whenever we delete something it goes into trash, if we want we can recover it later and if you don’t want to recover you can delete it permanently.

But mostly it happens that we delete some posts and don’t even remember to delete it permanently this makes database bigger in size, thus taking more time to process and making the site slow.

Just add the below lines of code in wp-config.php :

define('EMPTY_TRASH_DAYS', 7 ); // Empty trash after every 7 days

The above code will automatically empty trash every 7th day. thus cleaning up your database and making you website Optimized and faster.

1. How to turn off Post Revisions

WordPress has a really good feature of Auto save which automatically saves the post which is really beneficial in lots of cases, but sometime people complain that WordPress saves the posts too often and can create problems on heavy traffic websites, because it will require more resources.

So the Solution is to specify the Auto Save interval, which can be done by adding the below lines in WP-config.php :

define('AUTOSAVE_INTERVAL', 360 );  // seconds

The Interval is defined in seconds in the above code I have mentioned 360 Seconds = 6 minutes that means WordPress will save the post every 6 minutes

The default value is 60 Seconds that means WordPress saves a post every minute, but now you can change the Auto Save interval to whatever you want

      Your post, ".$post->post_title." has just been published. Well done!
   ";
   wp_mail($author->user_email, "Your article is online", $message);
