管理ページアクセス制限を有効にすると、サイトヘルスで「サイトでループバックリクエストが完了できませんでした」という文字が出るが、この問題、site-health.phpを除外設定にしてもなお出続ける。 制限をOFFにすると、出なくなる。 バージョン「1.5.1」でのアップデートで、この問題は解決したようです。ありがとうございました。

ワードプレスのデフォルトの仕様だと思いますが、/wp-admin/にアクセスするとプラグインで変更したログイン画面のurlヘリダイレクトされてしまいますのでこちらの改善もお願いいたします。 例) example.co.jp/wp-admin ↓ リダイレクト example.co.jp/プラグインで設定したログイン画面のURL文字列 個人的には下記のコードで対処しています。

add_action('init', 'remove_default_redirect');
add_filter('auth_redirect_scheme', 'stop_redirect', 9999);

function stop_redirect($scheme)
    if ( $user_id = wp_validate_auth_cookie( '',  $scheme) ) {
        return $scheme;

    global $wp_query;
    get_template_part( 404 );

Great tool, simple yet powerful.

Like the simplicity and efficiency of the plugin. One thing I would really like to change is CAPTCHA. C'mon guys, haven't you seen Google's reCAPTCHA? It's way much better, imo.

Warning, 'Rename Login Feature' is not secure, very easy to get around

By m6xkr on September 3, 2016

For the most part this is a nice plugin, I installed it because I was getting hundreds of strange access requests per hour from all over the world. While most are clearly automated and in all probability harmless, I thought this plugin would provide a layer of protection. After only a day of use I have found out that your "renamed" login can instantly be revealed to anyone who adds a simple string of characters at the end of your domain name. ...A bit disappointing, however I suppose most people may not find this loophole?
