Я смотрел на Google, и я пытался какое-то решение, которое ничем 't work как проверить, нет ли пробела перед первым) и т. д. Это мой код

      $this->load->library('alphabet'); 
      $this->load->view('accueil', $data); 
     } 
    }

<?php 
    class Alphabet 
    { 
     private $lettres = 'abcdefghijklmnopqrstuvwxyz'; 
     public function __construct() 
     { 

     }

Я не использую CodeIgniter, но сообщение «Не удается изменить информацию заголовка», как правило, если они вызваны вы вывели что-то на экран, а затем попытались сделать «header» («location: someFile.php»); «так что проверяйте на какой-либо вывод или разрывы в php, например'?> Joe

ошибка находится на config.php – Vinie

@Joe: Я проверил и было какое-то место до или после тега php. –
