Cannot modify header information - headers already sent by (output started at /data/home/

Posted 2023-03-16

Warning: Cannot modify header information - headers already sent by (output started at /data/home/qmu015180/htdocs/wp-content/themes/041b/functions.php:1) in/data/home/qmu015180/htdocs/xr-includes/pluggable.php on line 1743
这个事问题
if ( !$is_IIS && php_sapi_name() != 'cgi-fcgi' )
status_header($status);// This causes problems on IIS and some FastCGI setups
header("Location: $location", true, $status);
就是说的这行错误
希望大神解决一下

参考技术A 出这个错误是因为 header('Content-Type:text/html;charset= UTF-8');发送头之前不能有任何输出，空格也不行,你需要将header(...)之前的空格去掉,或者其他输出的东西去掉，如果他上面include其他文件了，你还要检查其他文件里是否有输出
请采纳答案，支持我一下。追问

<?php if (is_home()||is_search()) bloginfo('name'); else wp_title(''); print " 这就是那个header.php前面没有什么东西啊
