This plugin hasn’t been tested with the latest three major releases of WordPress. It may no longer be maintained or supported and may have compatibility issues when used with more recent versions of WordPress.

Remove custom fields meta box


This plugin disables the custom fields meta box that WordPress includes by default. The custom fields meta box includes a slow query, which on large sites can take 10+ seconds.

Do not install this plugin if you rely on the custom fields meta box. If you do not know what this means, you should probably not install this plugin. If you are using a plugin such as Advanced Custom Fields, Custom Field Suite, or similar, to manage your custom fields, don’t worry – these plugins will be unaffected.

The custom fields meta box performance is currently being discussed in Trac. If you find this plugin useful, you may want to follow that ticket.


Just install the remove custom fields meta box through WP Admin and you’re done. No complicated configuration or code changes required!


Do I need this plugin if I use the Advanced Custom Fields plugin?

Since ACF 5.6.0, ACF now disables the custom fields meta box itself. Therefore, you do not need to install this plugin, if you are already using ACF 5.6+

Do I need this plugin if I am using the new block editor (Gutenberg)?

The new block editor requires users to opt in to view the custom fields UI, meaning that the performance hit is not incurred for most users.

However, you may want to install this plugin if some of your users are using the Classic Editor plugin, as the classic editor is still impacted by this issue on WordPress 5+
