This plugin logs the activity of supported plugins to a file, making it easier to figure out why there’s a problem.
If you have been asked to install this plugin because of a support issue then installing this plugin is just like installing any other plugin. Once installed, go to Settings->WP Logger and enable logging. If you have a number of supported plugins enable the one you are interested in.
Developers who want to use this plugin to add logging to their own plugin should see the Developers section of this documentation.
Mark Jaquith’s <a href="https://wordpress.org/extend/plugins/monitor-pages/" rel="ugc">Monitor Pages</a> plugin was used as a template for this plugin. Thanks Mark!
<h4>Developers</h4>
Other plugins can use this plugin to record important events which are then dumped to a log file. Plugins must add the event to a global array in the following way:
<pre><code>$GLOBALS[ 'wp_log' ][ 'name_of_plugin' ][] = 'Some important event';
</code></pre>
Plugins must also add themselves to a list of enabled plugins. This will make it easier for blog owners to filter out which plugin they want to debug on the settings page. Add and edit the following code so it is executed when the plugin is loaded.
<pre><code>$GLOBALS[ 'wp_log_plugins' ][] = 'name_of_plugin';
</code></pre>
A hypothetical example might be a plugin (let’s call it “Big A”) that uses the output buffer to change the letter “a” to “A”. The events recorded by this might include the following:
<pre><code>$GLOBALS[ 'wp_log' ][ 'big_a' ][] = 'Created output buffer';
$GLOBALS[ 'wp_log' ][ 'big_a' ][] = 'Output buffer callback';
$GLOBALS[ 'wp_log' ][ 'big_a' ][] = 'Replaced a with A in page';
</code></pre>
This plugin takes the “wp_log” array and dumps it to a file in the upload directory of the blog it’s activated on. The file is linked from the plugin settings page and can be deleted on that page too. The file is a simple text file and is not protected in any way so be careful if auth cookies are logged by a plugin.
A “log” function isn’t included but if you want to add one to your plugin check the constant WP_DEBUG_LOG is defined before adding to the log array. If your plugin doesn’t use a class make sure that you call the log function a unique name so it doesn’t conflict with other plugins.
<pre><code>function log( $message ) {
 if ( defined( 'WP_DEBUG_LOG' ) )
 $GLOBALS[ 'wp_log' ][ 'name_of_plugin' ][] = $message;
}
</code></pre>

Simple History

<blockquote>
“So far the best and most comprehensive logging plugin” – <a href="https://wordpress.org/support/topic/so-far-the-best-and-most-comprehensive-logging-plugin/" rel="ugc">@herrschuessler</a>
</blockquote>
Simple History shows recent changes made within WordPress, directly on your dashboard, on a separate page, or in the admin bar.
The plugin acts as an audit log of the most important events that occur in WordPress.
It’s a plugin that is good to have on websites where several people are involved in editing the content.
No coding is required to use the plugin. Just install it and it will start logging events.
<h3>🔍 How Simple History Helps in Real Situations</h3>
Track what’s happening on your site 
“Has someone done anything today? Ah, Sarah uploaded the new press release and created an article for it. Great! Now I don’t have to do that.”
Identify issues and debug faster 
“The site feels slow since yesterday. Has anyone done anything special? … Ah, Steven activated ‘naughty-plugin-x’, that must be it.”
Keep Freelancers & Agencies Accountable 
“I hired a developer to optimize my site. But did they actually do anything? A quick glance at Simple History shows me exactly what they worked on, so I know I’m getting my money’s worth!”

<h3>📡 RSS feed with changes</h3>

<h3>🤖 WP-CLI commands for automation</h3>
<a href="https://simple-history.com/features/wp-cli-commands/?utm_source=wordpress_org&utm_medium=plugin_directory&utm_campaign=documentation&utm_content=readme_doc_wp_cli_commands" rel="nofollow ugc">Multiple WP-CLI commands exist</a>, to view and search the log, and to view more information about a specific event.
WP-CLI support is perfect for system administrators and agencies managing multiple WordPress sites. Using WP-CLI commands they can automate log monitoring, create reports, or integrate with existing DevOps tools.
Example commands:
<ul>
<li><code>wp simple-history event list</code> – List the latest logged events.</li>
<li><code>wp simple-history event get</code> – Get more information about a specific event.</li>
<li><code>wp simple-history event add</code> – Add a custom event to the log.</li>

<a href="https://simple-history.com/add-ons/premium?utm_source=wordpress_org&utm_medium=plugin_directory&utm_campaign=documentation&utm_content=readme_doc_stealth_mode" rel="nofollow ugc">Stealth Mode</a> allows Simple History to run completely in the background, hidden from the WordPress admin interface. This is ideal for agencies, developers, and administrators who want to track user activity discreetly without exposing the logs to other users.
There are two modes:
<ul>
<li>Partial Stealth Mode – Hides the plugin but allows selected users to access the logs.</li>
<li>Full Stealth Mode – Completely hides Simple History from everyone.</li>
</ul>
When Stealth Mode is enabled, the activity log remains accessible via the REST API, WP-CLI, and RSS feed, ensuring administrators can still retrieve logs when needed.
Stealth Mode is built into the core/free version and is enabled using constants or filters. The <a href="https://simple-history.com/add-ons/premium?utm_source=wordpress_org&utm_medium=plugin_directory&utm_campaign=documentation&utm_content=readme_doc_stealth_mode" rel="nofollow ugc">Simple History Premium</a> add-on provides a user-friendly GUI for managing Stealth Mode settings without writing code.

);

Simple History – Track, Log, and Audit WordPress Changes

This is a must have plugin in my eyes. It's an amazing plugin that lets you see ANY changes that are made to your website via the dashboard or cron system and I love seeing the changes, since now I know if a coworker already edited a certain page and what exactly changed without going to the revisions. 

It also helps me when a plugin has a bad update to troubleshoot issues and such. 

In my honest opinion, the benefits of this plugin are numerous and I wish something like this was in core since I love the concept so much.

Something that should be in core!


This is simply a great plugin.



Plug the RSS feed into a RSS reader, and you can monitor multiple sites for activity in one place.



Great work!!


Awesome plugin


I have a small number of plugins I install immediately on every site, and this is one of them. Just like the name says, it's simple, but provides a critical record of changes made on the site. I recently used it to resolve a massive issue where a client had deleted a user and inadvertently deleted all of their content.



This plugin didn't restore the content, of course — that's not what it's intended to do — but it helped me solve the mystery of what had happened, since the client didn't understand what they had done. So… install Simple History on your site! (And keep good backups. That was the rest of the story.)


Essential on every site I build
