Hi, I'm trying to export data from db into a csv file and also download it. The csv file is generated and stored correctly on the server, however, when I use File::download($filename), the file is downloaded but with the following warning in it: Warning!
ErrorException [ Warning ]: Cannot modify header information - headers already sent by (output started at \webserver\UniServer\www\quizz\fuel\core\classes\file.php:777)
COREPATH/classes/cookie.php @ line 95:

94: 
95: return setcookie($name, $value, $expiration, $path, $domain, $secure, $http_only);
96: }

My code is as follows:

  $quizzes = Format::forge($export) -> to_csv();
  
  $file_path = DOCROOT.'documents'.DS;
  $filename = time().'_export.csv';
  
  File::create($file_path, $filename, $quizzes);
  File::download($file_path.$filename);

Any help is appreciated. Thanks.
