Disable preview in the WordPress theme Customizer

Stanislav KhromovStanislav Khromov

The WordPress Customizer preview can be notoriously buggy. Here is a snippet for easily disabling the customizer preview:

add_action( 'customize_preview_init', function() {
    die("The customizer is disabled. Please save and preview your site on the frontend.");
}, 1);

After adding this code to your themes functions.php file or a plugin, the live preview will simply show a message that it is disabled.
