我在做什么错......这似乎不起作用......我不断收到以下错误

警告：无法修改标头信息 - 标头已由 /home/puretige/public_html/wp-includes/option 中的（输出开始于 /home/puretige/public_html/wp-content/plugins/Pure Tiger/puretiger.php:13）发送.php 在第 568 行

警告：无法修改标头信息 - 标头已由 /home/puretige/public_html/wp-includes/option 中的（输出开始于 /home/puretige/public_html/wp-content/plugins/Pure Tiger/puretiger.php:13）发送.php 在第 569 行

该插件在激活期间生成了 2 个字符的意外输出。如果您发现“标头已发送”消息、联合提要问题或其他问题，请尝试停用或删除此插件。

请注意我对此很陌生....

版权声明后删除关闭?>和打开标签。<?php2 换行防止 wordpress 发送标题。

add_action('admin_menu','register_my_custom_submenu_page');

检查此插件是否尝试写入 cookie。

如果是这种情况，那么您的插件必须在任何 html 代码处理之前启动。因此，您必须在 index.php 的顶部启动插件，然后<!doctype ... >

一些关于 cookie 的阅读：http: //php.net/manual/en/features.cookies.php
