Place in the functions.php file:

$func = function ($a) {
global $wp_version;
return (object) array(
'last_checked' =&gt; time(),
'version_checked' =&gt; $wp_version,
);
};
add_filter('pre_site_transient_update_core', $func);
add_filter('pre_site_transient_update_plugins', $func);
add_filter('pre_site_transient_update_themes', $func);

Reproduce this customization today

The principle of the hook remains useful, but the administration screens and WordPress APIs have evolved since the publication. Test the code in a staging environment with the exact version of the site's core, theme, and plugins.

Save the files and the database before making any changes.
Control user capabilities, nonces, input validation, and output escaping.
Place customizations in a dedicated plugin or a child theme to preserve updates.
