我是全新安裝phpBB 3的
完成後 當我試註冊時
上方出現如下 Warning

代碼: 選擇全部

Warning: Cannot modify header information - headers already sent by (output started at C:\AppServ\www\phpBB3\includes\functions.php:2914) in C:\AppServ\www\phpBB3\includes\functions.php on line 3391

Warning: Cannot modify header information - headers already sent by (output started at C:\AppServ\www\phpBB3\includes\functions.php:2914) in C:\AppServ\www\phpBB3\includes\functions.php on line 3393

Warning: Cannot modify header information - headers already sent by (output started at C:\AppServ\www\phpBB3\includes\functions.php:2914) in C:\AppServ\www\phpBB3\includes\functions.php on line 3394

Warning: Cannot modify header information - headers already sent by (output started at C:\AppServ\www\phpBB3\includes\functions.php:2914) in C:\AppServ\www\phpBB3\includes\functions.php on line 3395

在\includes\functions.php 內的第3391至3395行數如下

代碼: 選擇全部

	header('Content-type: text/html; charset=UTF-8');

	header('Cache-Control: private, no-cache="set-cookie"');
	header('Expires: 0');
	header('Pragma: no-cache');

我是用Apache/2.2.4 (Win32) PHP/5.2.3 MySQL 5.0
煩請告知 如何處理 謝謝
