Question

我做错了什么......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 - 已经发送的标头（/ home / puretige / public_html / wp-content / plugins / Pure Tiger / puretiger.php：13中的输出）/ home / puretige / public_html / wp-在第568行包含/ option.php

警告：无法修改标头信息 - 已经发送的标头（/ home / puretige / public_html / wp-content / plugins / Pure Tiger / puretiger.php：13中的输出）/ home / puretige / public_html / wp-在第569行包含/ option.php

插件在激活期间生成了2个意外输出字符。如果您发现“已发送标头”消息，联合供稿问题或其他问题，请尝试停用或删除此插件。

请注意我对此很新....

Answer 3

检查此插件是否尝试编写cookie。

如果是这种情况，则必须在任何html代码处理之前启动插件。所以你必须在<!doctype ... >

之前在index.php的顶部启动插件
