WordPress 5 Cookbook

How to do it...

Follow these steps to limit the number of allowed revisions for posts:

1. Open the wp-config.php file in the code editor.

2. Find the comment that says /* That’s all, stop editing! Happy publishing. */ inside the wp-config.php file and add the following line of code before the comment:

define( 'WP_POST_REVISIONS', 5 );

3. Save the changes to the file.

Now, the revisions will be limited to five per post. Follow these steps to check if the revisions are limited to five:

1. Log in to Dashboard as an administrator.
2. Use the Posts | Add New option to create a new post.
3. Click the Publish button to publish the post.
4. View the URL and get the ID of the created post. It should look similar to the following:
