WordPress多站点问题，因为我有一个主站点是http://example.com，另一个是http://example.com/subsite。
问题：
1) 当我点击一个名为test的菜单项时，它从http://example.com/subsite开始显示file not found。
2) 当我登录并点击名为test的菜单项时，它会完美地打开该页面，但当我编辑该页面进入该页面的管理面板时，它显示file not found
注意(test页面受密码保护)
3) 从管理面板，我访问了http://example.com/subsite子网站，然后它显示了该网站的管理面板，但它很奇怪，也没有加载css，也没有正确加载。
我的config.php文件如下

任何帮助都将不胜感激。
可能您(或某人)对数据库值进行了手动更改。所有这些问题可能都来自于一个问题——你的网站地址在数据库中被搞砸了。
要纠正这一点，第一个最简单的尝试可能是转到Settings > General并重新保存站点链接。如果这没有帮助，你需要在PhpMyAdmin中输入，检查表中的值：wp_blogs和wp_sites，左边的列应该分别有域名和右边的列应该有路径。
之后，转到每个子站点并单击Permalink->SAVE PERMALINKS，看看它们是否有效。
在我的案例中，发生错误是因为nginx充当反向代理服务器。在Plesk下，它可以在Tools & Settings > Services Management中被去激活。
