PHP故障排除通知：未知：1 ...哪里是未知令牌？

Question

我收到一个PHP错误，我需要帮助以解决问题：

  

[Fri May 08 10：20：41.234655 2015] [：error] [pid 6969] [client 207.183.229.82:3038] PHP注意：未知：1。h-＆gt; opened_pa​​th = [null] h-＆gt; filename = [/ var / www / example.com / htdocs / wp-admin / network / site-new.php] \ n在第0行的未知中，引用者：http://example.com/wp-admin/network/site-new.php

当我尝试添加新网站时，会在全新安装的WordPress上发生这种情况。

但是什么是未知的标记，为什么它未知？我查看了文件wp-admin/network/site-new.php的第0行，它只包含了php标记的开头：<?php

其他信息

当我POST加入Wordpress操作/wp-admin/network/site-new.php时会出现此错误。此尝试实际上将243条消息添加到我的错误日志中。以下是前三个：
