遇到多站点的子站点（新安装的3.9，没有插件或主题）在尝试访问子站点的wp admin部分时抛出404错误的问题。它在IIS7上运行。

• http://www.mysite.com/subsite/wp-admin -> 抛出404http://www.mysite.com/subsite2/wp-admin -> 抛出404http://www.mysite.com/wp-admin -> 当我们通过登录时，适用于主站点http://www.mysite.com/wp-admin 并导航到子站点，然后尝试注销它也会抛出404。

  正在使用default web.config, 对于重写规则。但所有子站点都在css/js文件上抛出了404个错误。因此，我稍微修改了重写规则，您可以在下面看到。

  我是否缺少任何其他重写规则或需要更改？因此，子网站在导航到/wp admin页面时不会引发404错误。
