WordPress Post Revisions Made Simple: A Step by Step Guide

“Where did my original content go?” That’s a panic-filled message we often get from WordPress users who have made unwanted changes to their posts.

What many don’t realize is that WordPress automatically saves previous versions of their content. They just need to know where to look.

At WPBeginner, we regularly use the WordPress Revisions feature to recover deleted content, fix mistakes, and restore earlier versions of our posts.

We’ve also helped many users understand how powerful this tool really is. It’s not just about bringing back lost content, but about giving you the freedom to edit confidently, knowing you can always revert to a previous version if needed.

In this step-by-step guide, we’ll show you how to easily undo changes in WordPress with post revisions. You will learn how to recover old versions of your posts, compare changes, and manage revisions effectively.

Here is an overview of the topics we will cover in this guide:

What Is the Post Revisions Feature?

Post revisions is a WordPress website feature that allows you to undo changes and go back to an earlier version of your posts and pages.

For each draft you are working on, WordPress automatically saves a temporary revision. This type of revision is called auto-save.

WordPress stores an auto-save every 60 seconds. It also automatically replaces the older version with the new auto-save.

The autosave feature helps you restore the content if something goes wrong before you can save it. For example, if your browser crashes or your computer freezes while you’re writing, you can restore your latest draft.

WordPress also saves post revisions each time a user clicks on the save, update, or publish button. Unlike auto-saves, these revisions are permanently stored in the WordPress database.

You can locate, browse, and revert to any of these WordPress revisions from the post-edit screen.

Why You Should Use Post Revisions

Almost every WordPress user can benefit from post revisions. Writing great content requires a lot of tweaking and editing. WordPress revisions allow you to see your process and take a bird’s eye view of how your post has evolved.

You can then switch between different states of your draft, make changes, and make your article perfect for publishing.

For multi-author WordPress sites, post revisions allow editors to easily manage the work of multiple authors. You can see who made changes to an article, what changes they made, and so on.

That being said, let’s take a look at how to use post revisions to improve your WordPress posts and pages.

How to Use Post Revisions to Undo Changes in WordPress

WordPress displays the number of revisions under the ‘Post’ section in the Settings panel on the right.

You can find that on the right-hand side of your post editor screen. Clicking on the ‘Revisions’ will take you to the post revisions screen.

The post revision screen will show you the latest revision of the post, with a scrollbar at the top.

Sliding the button on the scroll bar will take you to earlier revisions of the post.

Changes made in each revision will be highlighted in green and pink colors. On top, you can see the user who made these changes, the time, and other information.

WordPress will also let you know if a revision is an autosave or a draft.

You can use the next and previous buttons to move around revisions.

Plus, you can check the box at the top that says ‘Compare any two revisions.’ Doing so will split the scrollbar button into two, and you can take each button to a different revision and compare the differences between them.

To restore a revision, you can simply click on the ‘Restore This Revision’ or ‘Restore This Autosave’ button.

WordPress will restore the selected revision as your current post revision, and you can then save it as a draft.

Keep in mind that reverting to an earlier revision will not delete the latest version of your post. Instead, WordPress will store it in the database as another revision.

Using Post Revisions with Classic WordPress Editor

In case you haven’t upgraded your WordPress to Gutenberg and are still using the Classic Editor, then you’ll find the post revisions in the publish meta box on the right panel of the post/page edit screen.

To view the post revisions, you can simply click the ‘Browse’ link next to the number of revisions. Apart from this, the post revisions work similarly in both the Classic Editor and Gutenberg.

Limiting Post Revisions in WordPress

All post revisions are stored in your WordPress database. Due to this, many users worry that too many revisions can slow down their websites.

This is not true.

WordPress skips post revisions when making database calls on the front end. It only looks for revisions on the post edit screen or when you are actually browsing revisions.

You can still control and limit post revisions in WordPress. We’ll show you two different methods, and you can choose the one that best suits you.

1. Limit Post Revisions in WordPress Using a Plugin

The easiest way to manage WordPress post revisions is by using a plugin. This allows you to control revisions from the WordPress admin area.

The first thing you need to do is install and activate the WP Revisions Control plugin. For more details, see our step-by-step guide on how to install a WordPress plugin.

Upon activation, you need to visit the Settings » Writing page and scroll down to the WP Revisions Control section.

From here, you need to enter the number of revisions you want to store for each post type and then click on the ‘Save Changes’ button to store your settings.

WP Revisions Control will now limit the post revisions stored in your WordPress database.

The plugin also allows you to delete revisions for an individual post. Simply edit the post where you want to delete revisions and scroll down below the editor.

You can limit the revisions for this post only or delete them by clicking on the ‘Purge these revisions’ button.

2. Limit WordPress Post Revisions Manually

WordPress allows you to control how many revisions you want to keep for an article. To limit post revisions, you can add this code to your WordPress site’s wp-config.php file:

define( 'WP_POST_REVISIONS', 10 );

Don’t forget to replace 10 with the number of revisions you want to keep for each post.

To make it easier, you can use WPCode. It is the best code snippet plugin for WordPress, and it helps you add custom code without risking breaking your site.

During testing, we found that it also has a library of 2000+ ready-made code snippets, including one for limiting post revisions. To learn more, see our WPCode review.

First, you need to install and activate the free WPCode plugin. If you need help, you can follow our tutorial on how to install a WordPress plugin.

Upon activation, go to Code Snippets » Library from the WordPress admin dashboard.

Then, search for the ‘Limit Post Revisions’ snippet. Once you find it, hover over it, and click the ‘Use snippet’ button.

From there, WPCode will automatically add the code that limits the post revisions storage memory to 4.

However, you can replace 4 with the number of your choice.

After that, simply toggle the switch at the top of the page from ‘Inactive’ to ‘Active’.

Then, hit the ‘Update’ button.

That’s it. You’ve now successfully limited how many post revisions WordPress will store.

How to Delete Old Post Revisions in WordPress

Old post revisions are perfectly harmless, and you don’t need to delete them in most cases. However, if you have a very large website with thousands of articles, then deleting old post revisions can help you reduce backup sizes.

First, you’ll need to install and activate the WP-Optimize plugin. For more details, see our step-by-step guide on how to install a WordPress plugin.

Upon activation, go to the WP-Optimize » Database page and check the box next to the ‘Clean all post revisions’ option.

Now, click on the ‘Run optimization’ button to delete all post revisions. Once you have cleaned up the revisions, feel free to uninstall and delete the plugin.

To learn more about this plugin, see our detailed WP-Optimize review.

Deleting WordPress Post Revisions via phpMyAdmin

Advanced users can also delete WordPress post revisions via phpMyAdmin.

First, make sure that you have created a complete WordPress database backup.

After that, simply log in to your WordPress hosting control panel and click on the phpMyAdmin icon.

Next, you need to select your WordPress database from the left column. phpMyAdmin will now display tables in your WordPress database.

After that, you need to click on the SQL tab from the top menu.

This will load phpMyAdmin’s SQL interface. From here, you can manually run commands on your WordPress database.

You need to enter the following code:

DELETE FROM wp_posts WHERE post_type = "revision";

Don’t forget to replace wp_ with your own WordPress database prefix. After that, click on the ‘Go’ button to run the command.

phpMyAdmin will now delete all revisions from your WordPress database.

How to Completely Disable WordPress Post Revisions

We don’t recommend disabling WordPress post revisions. However, some users may want to disable revisions to reduce their WordPress database size.

The easiest way to do this is by installing the Disable Post Revision plugin. For more details, see our step-by-step guide on how to install a WordPress plugin.

Upon activation, go to the Settings » Writing page and select the post types where you want to disable the revisions feature.

Don’t forget to click on the ‘Save changes’ button to store your settings.

If you don’t want to use the plugin, then you can also do the same thing manually by adding this code to your wp-config.php file:

define('WP_POST_REVISIONS', false );

This code disables the WordPress post revisions feature on your website. It will still allow WordPress to save one autosave and one revision in your browser storage.
