To turn on automatic updates for major WordPress core releases, sign in to WordPress and open Dashboard > Updates. If the page says your site receives maintenance and security releases only, select “Enable automatic updates for all new versions of WordPress.” That setting applies to WordPress core, not plugins or themes.

Enable major updates from the WordPress dashboard

  1. Sign in to your WordPress administration area.
  2. Open Dashboard > Updates.
  3. Find the core-update settings message. If it says the site is automatically kept up to date with maintenance and security releases only, select “Enable automatic updates for all new versions of WordPress.”
  4. Confirm that the page now reports automatic updates for each new WordPress version.

The dashboard wording refers to new WordPress core versions, including major releases. It does not turn on automatic updates for plugins or themes.

Enable major core updates in wp-config.php

If you manage site configuration in code, add this definition to wp-config.php:

define( 'WP_AUTO_UPDATE_CORE', true );

The values have different effects:

Value Core updates enabled Effect on the dashboard control
true Development, minor and major releases The constant overrides the user-controlled setting.
'minor' Minor releases only Major releases remain disabled.
false None of the core update types controlled by this constant The constant overrides the user-controlled setting.

Use the constant only when its broader behavior is acceptable: true enables development updates as well as minor and major releases. A defined WP_AUTO_UPDATE_CORE value takes precedence over the setting a user can change on Dashboard > Updates.

Elebase USB to USB C Adapter for iPhone 18 Pro Max,USBC Car Charger Adapter
  • Read Before You Buy — No Video Output: These adapters support charging and USB 2.0 data transfer, but cannot transmit video signals. Except for standard USB webcams (which use USB data only), they are not compatible with HDMI/DisplayPort cables, video-capable USB-C hubs, or docking stations with video output.
  • Convert USB-A Ports to USB-C: Designed to connect USB-C earphones, cables, flash drives, card readers, and other USB-C accessories to standard USB-A ports. Plug-and-play with no drivers or software required.

  • 12-Month Warranty: Backed by a 12-month manufacturer warranty for peace of mind. Designed to meet strict quality control standards for reliable everyday performance.

Use a filter when you need selective control

For developer-managed policies, WordPress provides the allow_major_auto_core_updates filter. The WordPress handbook recommends putting update filters in a must-use plugin. Do not place add_filter() calls directly in wp-config.php; WordPress is not fully loaded there, and this can conflict with tools such as WP-CLI.

Why the automatic-update option may be missing

If the link to enable all new versions is unavailable, check these conditions before treating the dashboard as broken:

  • A configuration constant is defined. WP_AUTO_UPDATE_CORE can force a policy and override the dashboard control.
  • Automatic updates are disabled globally. A defined AUTOMATIC_UPDATER_DISABLED constant prevents background updates.
  • A filter or other updater restriction is active. Code in a must-use plugin, another plugin, or the site’s deployment setup can restrict core updates.
  • WordPress detected a version-control checkout. New installations normally enable major updates by default, but WordPress with a detected version-control checkout is an exception.

Inspect wp-config.php, must-use plugins and deployment code for these controls. If a managed host or organization maintains the configuration, its policy may need to be changed by an administrator rather than from the dashboard.

Understand the default behavior by installation age

WordPress introduced automatic background updates in version 3.7, initially covering minor core releases and translations. Starting with WordPress 5.6, new installations have both minor and major core updates enabled by default unless WordPress detects a version-control checkout. Existing installations keep their previous behavior until an administrator, constant or filter enables major updates.

These defaults explain why two sites on the same WordPress version can show different update settings: installation history and environment detection matter.

Core updates are separate from plugin and theme updates

Enabling major WordPress releases changes the update policy for WordPress core only. Plugin and theme automatic updates have separate controls, including per-plugin and per-theme settings. Review those independently if you want them updated automatically.

Should you enable major updates on a production site?

For a straightforward site using well-supported themes and plugins, automatic major core updates reduce the chance of leaving the site on an old release. Sites with custom code, tightly controlled deployments or version-controlled files deserve more care.

Test customized sites on staging first

The WordPress handbook identifies staging as a way to allow testing time before a major update reaches production. Reproduce the production configuration on staging, apply the major release there, and check the site’s key workflows before allowing the same change on the live site.

Quick verification checklist

  • Open Dashboard > Updates and confirm the page reports automatic updates for new WordPress versions.
  • Check whether WP_AUTO_UPDATE_CORE or AUTOMATIC_UPDATER_DISABLED is defined.
  • Review must-use plugins and other updater filters if the control is missing.
  • Check for a version-control checkout, especially on a newer installation.
  • Remember that plugin and theme update policies are configured separately.
