Have you ever found yourself in a situation where, after spending much effort editing a post, something happens and you suddenly find that you have lost all of your hard work because you forgot to hit the ‘Save’ button as you went along?
If this ever happens, there’s no need to feel alarmed! WordPress comes with a powerful autosave and content recovery management system that:
- Automatically saves earlier versions of your posts,
- Gets your page or post back if something happens to your computer or browser while you’re working, and,
- Lets you recover an older draft if you changed the content in an article.
In this tutorial, we show you how to use the autosave and content recovery management system of WordPress to restore content in your pages and posts.
Content Recovery And Autosave Function Of WordPress: Tutorial
Usually, when you update a post or page, you will see a confirmation message like the one below …
(Edit Post – Post updated successfully!)
WordPress post revisions ensure that your content is saved periodically, allowing you to undo changes to your drafts and restore older post revisions when something unexpected happens, for instance:
- Your internet connection goes down,
- Your internet browser crashes,
- You experience a temporary power outage,
When this happens and you try to save your work, a ‘WordPress Failure Notice’ like this may end up being displayed on your screen instead …
(WordPress Post Save Error Message)
If you see a message that says Are you sure you want to do this? Please try again displayed and click on the ‘Please try again’ link, you will normally return to an edit screen displaying an older version of your post, minus any changes that you recently made.
This is where WordPress ‘autosave’ can help prevent a disaster.
The Autosave Feature
In WordPress, autosave automatically enabled for all posts and pages, but this does not overwrite any content that has already been published.
By default, posts are autosaved to the database every sixty seconds. This interval can be changed by modifying code in your wp-config.php file.
Always make a backup of your website before making any modifications to important website files.

WordPress Revisions – Plugins
As mentioned earlier, there are some changes you can make to the WordPress revisions feature such as changing the autosave interval or even disabling the feature altogether, but these usually involve making modifications to code in WordPress files. If you don’t feel comfortable editing code, then contact your web host or get professional assistance.
Let’s focus, then, on some additional areas of WordPress post revisions function that don’t require messing around with code.
Post Editor Screen – Viewing The Revisions Box
As soon as you edit and update a page or post, WordPress begins to store new revisions for the content in its database. These appear in a Revisions list below your post or page …

Revision Management WordPress Plugins
Autosave and post revisions are no doubt functions that help make work more efficient. If you write a lot of content, however, after a while the revisions can start building up. This can significantly bloat the size of your WordPress database, so it’s important to also be able to manage your revisions.
(Your database could be storing lots of unnecessary data)
For example, if there are 250 posts published on your site with an average of 10 revisions each your database could be storing up to 2,500 copies of old data. If your post is approximately 100KB data, then with 2,500 revisions of that post, the total space wasted is about 250MB.
The good news is that there are some great free plugins for WordPress that can help you control your revisions and reduce the size of your database.
