How WordPress Auto Update Works: A Complete Guide
WordPress auto updates are an essential feature for every website owner who values security, efficiency, and peace of mind. If you’ve ever worried about staying on top of the latest security patches or compatibility issues, you’re not alone. Understanding how WordPress handles automatic updates—and how to enable, disable, or manage them—will empower you to keep your site safe and running smoothly. Let’s break down everything you need to know.
What Is WordPress Auto Update?
Automatic updates in WordPress refer to the platform’s ability to update itself, its plugins, or its themes without manual intervention from you, the site owner. WordPress introduced auto-updates to help users keep their sites secure and up to date, even if they forget or are unavailable to update manually.
Automatic updates can apply to:
- Core WordPress software
- Themes
- Plugins
By default, WordPress will automatically update for minor core releases and security patches. However, you can configure it to update for major releases, plugins, and themes as well.
Types of WordPress Automatic Updates
WordPress divides its auto-update process into several categories, each serving a distinct purpose:
1. Core WordPress Updates
WordPress itself gets updated in two ways:
- Minor Core Updates: These are small, incremental security and maintenance fixes (for example, 6.3.1 to 6.3.2). WordPress applies these automatically by default to protect your site from vulnerabilities.
- Major Core Updates: These are larger updates (like 5.9 to 6.0) that often include new features and significant improvements. By default, these are not automatically applied unless you enable this setting.
2. Plugin Updates
Plugin developers regularly release updates—sometimes for added features, but often to patch security vulnerabilities. WordPress allows you to choose which plugins auto-update, ensuring greater control and compatibility.
3. Theme Updates
Themes get updated for similar reasons as plugins. You can opt in or out of automatic theme updates, helping you maintain your site’s look and functionality.
How Automatic Updates Work in WordPress
Understanding the mechanism behind auto-updates helps in managing them wisely:
- WordPress schedules checks periodically to see if updates are available for core, plugins, or themes.
- If updates are found, WordPress downloads, installs, and activates these updates automatically if auto-updates are enabled for that component.
- If an update fails, WordPress reverts to the previous version, ensuring your site isn’t left broken.
You’ll typically receive an email notification when core, plugin, or theme updates are applied.
Enabling or Disabling Automatic Updates
Controlling auto-updates in WordPress is straightforward and can be achieved in several ways. Here’s how you can manage auto-updates for each component:
For Core Updates
1. Enable Major Version Auto-Updates
WordPress only auto-updates minor versions by default, but you can enable major version auto-updates by adding this line to your wp-config.php file:
define('WP_AUTO_UPDATE_CORE', true);
2. Disable All Automatic Core Updates
If you prefer to handle everything manually, you can disable all core updates by using:
define('WP_AUTO_UPDATE_CORE', false);
Tip: Always backup your site before modifying your
wp-config.phpfile.
For Plugin and Theme Updates
1. Using WordPress Dashboard
Starting from version 5.5, WordPress provides easy toggle switches for auto-updates:
- Plugins: Go to
Plugins>Installed Pluginsand click ‘Enable auto-updates’ next to the plugin of your choice. - Themes: Go to
Appearance>Themes, click on a theme, and select ‘Enable auto-updates’.
2. Managing with Filters
For more granular control, developers can use code snippets (filters) in the functions.php file:
- Enable all plugin auto-updates:
php
add_filter('auto_update_plugin', '__return_true');
- Enable all theme auto-updates:
php
add_filter('auto_update_theme', '__return_true');
Note: Code changes are best made within a child theme or site-specific plugin to avoid losing them during updates.
3. Using Plugins for Advanced Control
Management plugins like “Easy Updates Manager” offer a user-friendly interface and advanced scheduling for auto-updates. They allow you to decide exactly which plugins, themes, or core files get updated (and when).
Pros and Cons of WordPress Automatic Updates
Before you turn on or off any automatic update feature, weigh the following benefits and challenges:
Benefits
- Security: Immediate patching of security vulnerabilities keeps hackers at bay.
- Convenience: No need to log in and update manually every time.
- Bug Fixes: Quick application of performance improvements and bug fixes.
- Peace of Mind: Reduces the risk of forgetting critical updates.
Potential Challenges
- Compatibility Issues: An update might break a plugin or theme, especially if they rely on old code.
- Loss of Customization: Custom changes to plugin or theme files can get overwritten.
- Site Downtime: Although rare, a failed update could cause errors or downtime.
- Email Notifications: Frequent notifications could clutter your inbox if you manage multiple sites.
Best Practices for Managing Automatic Updates
To get the most out of WordPress auto updates while mitigating risks, follow these practical tips:
1. Always Backup Before Updates
Schedule regular backups—daily for active sites, at least weekly for static ones. This ensures you can restore your website quickly if an update causes issues.
2. Test Updates in a Staging Environment
Create a staging copy of your site to test new updates before applying them to your live site. Many web hosts offer one-click staging.
3. Monitor Site Health After Updates
Check your website immediately after updates. Use uptime monitoring tools to alert you if your site goes down.
4. Review Update Email Notifications
Read the email summaries sent after updates. These provide useful details in case you need to troubleshoot.
5. Maintain Plugin and Theme Quality
Uninstall unused plugins or themes. Stick with those from reputable developers with a track record for compatibility and timely updates.
6. Use Management Plugins Wisely
For advanced control, consider trusted update management plugins. They provide schedules, logs, and granular control.
7. Stay Informed About New Updates
Follow WordPress news and development blogs to understand what’s new in upcoming releases, potential issues, and recommended actions.
Practical Advice: When to Use Automatic Updates
- Small Brochure Sites: Enable all auto-updates (core, plugins, themes). The risk of breakage is low.
- E-Commerce or Membership Sites: Enable auto-updates for minor core, but manually update plugins, themes, and major core releases after testing.
- Custom-Built or Heavily Customized Sites: Use staging environments and manual updates to safeguard custom code.
Cost Considerations
Most features for managing automatic updates are completely free within WordPress itself. If you use a premium plugin or rely on a managed hosting provider, there might be added services—like automated testing or advanced backup systems. Always check what’s included in your hosting plan.
Furthermore, investing in professional backup solutions or managed services can offset the potential cost of emergency site repairs due to issues from automatic updates.
Summary
WordPress automatic updates simplify website maintenance and enhance security by ensuring your core, plugins, and themes stay current without constant manual attention. While the feature delivers peace of mind, it’s not a “set and forget” solution. Always combine auto-updates with best practices like frequent backups, staging tests, and post-update checkups.
Ultimately, how you use WordPress auto-updates depends on your comfort level, the complexity of your site, and how much time you can spend on maintenance. With the right setup, you can harness the best of both convenience and control.
Frequently Asked Questions (FAQs)

5. Are automatic updates safe for e-commerce or membership sites?
While auto-updates are generally safe, mission-critical sites should use them cautiously. Enable auto-updates for minor core releases and security patches, but test major updates, plugins, and themes in staging before updating your live site.
Mastering WordPress auto updates isn’t complicated—with a thoughtful approach, you’ll enjoy a more secure, stable, and hassle-free website!
