FAQ

Some plugins are still in the native language when switching to English

To fix this, move the file /wp-content/plugins/english-wp-admin/english-wp-admin.php to /wp-content/mu-plugins/

This will ensure this plugin is loaded before all other plugins and that it sets the correct language. This is a WordPress restriction.

Why are some URLs whitelisted?

update-core.php is whitelisted because translation updates do not work properly if you change locale on that screen.

options-general.php is whitelisted due to Trac issue #31318 and #29362

How do I whitelist a specific page from being translated

Use the english_wordpress_admin_whitelist filter. It takes a preg-style regular expression.

/** Whitelist /wp-admin/options-general.php?page=my_plugin **/
add_filter('english_wordpress_admin_whitelist', function($whitelisted_urls)
{
    $whitelisted_urls[] = '.*\/wp-admin\/options-general.php\?page=my_page$';
    return $whitelisted_urls;
});

How do I prevent regular users from having the option of changing the admin language?

If you only want the first admin user to have this option, put this code in your themes function.php file:

/** Only allow the admin user to change the admin language **/
if(get_current_user_id() === 1) {
    add_filter('english_wordpress_admin_show_admin_bar', '__return_true');
}
else {
    add_filter('english_wordpress_admin_show_admin_bar', '__return_false');
}

How do I automatically enable this plugin for certain users?

Use the snippet below to have admins always use the admin page in english.

/** Enable the plugin automatically for admin users */
if(current_user_can('manage_options')) {
    global $english_wordpress_admin_plugin;
    $english_wordpress_admin_plugin->set_cookie(1);
    add_filter('english_wordpress_admin_show_admin_bar', '__return_false');
}
