如果您查看错误消息，它会告诉您确切的情况，让我们对其进行分解：

Fatal error: Uncaught Error: Call to undefined function mysql_real_escape_string()

这意味着您遇到致命错误（因此当前请求将在此处终止/停止），致命错误为undefined function mysql_real_escape_string()，这意味着该功能不存在。

在堆栈跟踪中，您可以看到/home/exampdte/public_html/wp-content/plugins/permalink-finder_bak/includes/pf-404.php:621，这意味着该文件在行621上存在问题。

mysql_real_escape_string()（以及其余mysql_函数）已被弃用，并替换为mysqli_real_escape_string()和相关的mysqli_函数。

因此，您要么拥有permalink-finder_bak插件的过时版本，要么如果他们停止维护它，则需要停用它。
