安装wordpress出现:Warning: Cannot modify header information - headers already sent (output started at...)错误解决方案

在安装wordpress过程中,不断头部出现Warning: Cannot modify header information - headers already sent (output started at...)的错误提示,但仍然能继续安装完成。但是,当安装完登录时,页面上会直接显示出全部类似的错误,如:

 

Warning: Cannot modify header information - headers already sent by (output started at /www/htdocs/yoozhu/wp-config.php:1) in /www/htdocs/wordpress/wp-login.php on line 255

查了下原因和解决方法。主要是因为我之前在wp-config.php里曾经用记事本编辑过数据表的文字编码:define('DB_CHARSET', 'utf8');造成UTF8编码和BOM冲突,解决办法:使用写字板、UltraEdit、EditPlus等编辑器重新编辑文件保存。并回想起Ucenter安装介绍中说过UTF-8 编码的程序文件不建议使用 Windows 的“记事本”。
