It’s important to keep post revisions under control or they will quickly fill up your database. If you’re looking to limit the number of post revisions in WordPress, there are a few methods you can use. The easiest one is to simply edit your wp-config.php file and add a line of code that defines how many revisions to keep.
To limit the number of post revisions, you only need to make a small change in your wp-config.php file.
To limit the number of post revisions in WordPress, simply add the following line to your wp-config.php file:
define('WP_POST_REVISIONS', 5);
The number you choose will become the limit for revisions per post. In this case, it will be 5.
Before you add this line of code, search for WP_POST_REVISIONS in your wp-config.php file, and if you find it, just change the true or false value to the number of revisions you want.
