CodeIgniterのリダイレクト機能がライブサーバで動作しないが、localhost上で正常に動作する理由

Question

インストール後。私はデフォルトのコントローラとしてログインを設定し、adminのダッシュボードに行きたいですが、ダッシュボードにリダイレクトするのではなくログインの詳細を送信した後、再びコントローラをインストールするようにリダイレクトしています。

誰でも助けてくれますか？

マイログインコントローラはlogin.phpです：

<?php 
if (!defined('BASEPATH')) 
    exit('No direct script access allowed');

    function __construct() 
    {

     $this->load->database(); 

    }

あなたがライブサーバーにクッキーをチェックしましたか？私はあなたのような何かを経験しました。 redirect()の機能はライブサーバーでは機能しませんでしたが、実際にはうまくいかないのはuser_dataセッションが毎回ロードされたことです。私はちょうどライブサーバーのクッキー$config['sess_cookie_name'] = "MY-COOKIE*******"を許可し、すべてがうまくいく。
