わかりましたので、最初の codeigniter プロジェクトの作成に成功し、CMS 認証に Tank Auth を使用しました。私のMAMPインストールではすべて正常に機能し、ホストにアップロードされると引き続き機能します。
次に、mamp インストールでファイルを新しいプロジェクトに複製し、いくつかの構成設定 (新しいデータベース、ベース URL など) を変更しましたが、すべて問題なく動作します。この新しいプロジェクトがサーバーにアップロードされると、CMS にログインできません。
フォームは送信されたように見えますが、ログイン ページが再度読み込まれます。無効なユーザー名/パスワードに対してエラーは発生しません。
登録フォームを使用しようとすると、同じことが起こり、送信され、エラーはなく、ページが更新されたように見え、ユーザーは作成されません。
これは本当にイライラするので、何を試すべきかについてのアイデア！エラーがないため、タンク認証ライブラリが機能していないかのようです。

別のドメイン名でありながら同じサーバーにアップロードしましたが、正常に動作します。これは明らかにコーディングの問題ではありませんが、誰かが光を当てたり、提案をしたりすることができれば、それは大歓迎です
