除了以前的解决方案之外。我找到了丢失的css和脚本文件。

解决方法是

RewriteEngine On
RewriteBase /
RewriteRule ^index\\.php$ - [L]

# uploaded files
RewriteRule ^([_0-9a-zA-Z-]+/)?files/(.+) wp-includes/ms-files.php?file=$2 [L]

# add a trailing slash to /wp-admin
RewriteRule ^([_0-9a-zA-Z-]+/)?wp-admin$ $1wp-admin/ [R=301,L]

# Fix using the previous answer. 
RewriteRule ^admin/(.*)$ wp-admin/$1 [QSA,L] 

RewriteCond %{REQUEST_FILENAME} -f [OR]
RewriteCond %{REQUEST_FILENAME} -d
RewriteRule ^ - [L]
RewriteRule  ^[_0-9a-zA-Z-]+/(wp-(content|admin|includes).*) $1 [L]

#Fix to load css js image files for multi site admin urls. 
#old code RewriteRule  ^[_0-9a-zA-Z-]+/(.*\\.php)$ $1 [L]
RewriteRule  ^[_0-9a-zA-Z-]+/(.*\\.(php|css|js|png|jpg|gif))$ $1 [L]

RewriteRule . index.php [L]
