    こんにちは。

    まずは、デバッグモードを有効にするか、サーバのエラーログ等をご確認いただき、どのようなエラーメッセージが表示されているかをご確認下さい。

    返信ありがとうございます。

    デバッグモードを有効にしましたところ、HPのトップ画面に以下の文言が現れました。

    Deprecated: ltrim(): Passing null to parameter #1 ($string) of type string is deprecated in /var/www/html/wp-includes/wp-db.php on line 3030

    丸投げするようで申し訳ありませんが、これをどう解釈すべきなのでしょうか?
    ご教示ください。お願いいたします。

    こんにちは。

    Deprecated: ltrim(): Passing null to parameter #1 ($string) of type string is deprecated in /var/www/html/wp-includes/wp-db.php on line 3030

    →このエラーは、サイトが閲覧出来ないようなクリティカルなエラーではなく、今回の症状とは関係が無いと思います。

    ログイン時に「重大なエラーが発生しました」と表示されたとの事なので、同じ操作(おそらくログイン試行)を行った時に、代わりに何かエラーメッセージが表示されていないかご確認下さい。

    また、最初に申し上げた通り、サーバのエラーログをご確認下さい。
    ※エラーログの確認方法は、サーバ会社にお問い合わせください。

    初心者です。お世話になります。

    >ログイン時に「重大なエラーが発生しました」と表示されたとの事なので、同じ操作(おそらくログイン試行)を行った時に、代わりに何かエラーメッセージが表示されていないかご確認下さい。

    ログイン画面(ユーザー名、パスワード入力画面)にすると、今度は以下のようなメッセージが現れました。

    エラー: 予期しない出力により Cookie がブロックされました。ヘルプが必要な場合はこちらのドキュメンテーションを参照するか、サポートフォーラムをご利用ください。

    この「予期しない出力」とは何でしょうか?

    >サーバのエラーログをご確認下さい。

    ラズパイ3B+でサーバを組んでおり(雑誌記事に習った)、済みませんが詳しいことはわかりません。
    ただ、WordPress自体のアップデート、プラグインのアップデートは行われているようなのです。これはその都度メールで通知が来るので、問題なしと理解しています。いつの間にか、ログインできなくなっていたというのが実情です。

    こんにちは

    「予期しない出力」とは、大抵の場合、エラーメッセージです。
    Cookie はサーバーがレスポンスを返す前にヘッダ情報として返される必要があります。
    しかし、先にエラーメッセージがレスポンスとして返されたために、Cookie がブロックされた、ということだと思われます。

    何が起こっているのか知りたければ、@wildworks さんの仰る通り、サーバーのエラーログを確認してください。

    @jazzwalker1 さん

    こんにちは。
    エラーを見た限りでは原因は特定出来ませんでしたが、一旦テーマ・プラグインを強制的に無効化してみてはいかがでしょうか。

    管理画面には入れませんが、wp-content/themeswp-content/plugins直下のフォルダをリネームすれば無効化出来ると思います。

    例えば、エラーメッセージ内に/var/www/html/wp-content/plugins/contact-form-7とあり、このプラグインが一つの原因かもしれませんので、

    /var/www/html/wp-content/plugins/contact-form-7

    /var/www/html/wp-content/plugins/_contact-form-7
    などとリネームしてみる方法です。

    アドバイスに感謝いたします。

    >wp-content/themesやwp-content/plugins直下のフォルダをリネームすれば無効化出来ると思います。

    両方をやってみましたが、結果は駄目でした。テーマをリネームした場合には、HP自体が表示されずに、エラーメッセージの羅列となりました。

    手詰まりです。
    他にお気づきの点がありましたら、お知らせください。

    こんにちは

    WordPress のバージョンを 5.9 以降にするか、PHP のバージョンを 8.0 以前に変更してください。

    WordPress の手動更新の方法は以下にあります。

    ご教示ありがとうございます。早速、手動アップグレードをしてみました。

    ダッシュボードに入るところまでは行き着きました。
    ですが、肝心のHPを表示できません。

    以下のようなエラーが出ています。コメント頂ければ有り難いです。

    手動更新がうまくいっていないように思います。

    ご教示ありがとうございます。

    リンク先の情報(ファイルの上書き:wp-settings.php)で、HP自体は表示されるようになりました。
    一方で、今度はダッシュボードに入れなくなってしまいました。ログインができません。

    ちゃんとwp-settings.php は先に手動更新したバージョンと同じものでしょうか?
    手動更新がどこがうまくいっていない(ちゃんとアップロードできていない)かははっきり分からないので、手動更新自体をやりなおしたらどうかなと思います。

    トピック投稿者 jazzwalker

    (@jazzwalker1)

    お手数かけました。

    手動更新をやり直しました。ただ、それだけでは済まず、ある箇所でパーミッションの問題が生じ、すべて「許可」にしました。試行錯誤しました。

    何とか、HPが表示でき、ダッシュボードにも入れるようになりました。

    ただ、デバッグモードからも出たので、デバッグモードに戻した場合、多くのエラー、ウォーニングが出ているものと思われます。そのことが気がかりです。

    munyagu

    (@munyagu)

    デバッグモードでは Deprecated のメッセージが出ているかもしれませんが、それは WordPress がまだ十分に php8.1 に対応できていないためです。
    当面は動作には問題ありません。
    気になるようでしたら、php8.0 や 7.x に変更ください。

    参考)WordPress 5.9 and PHP 8.0-8.1
