错误路径 css 和 javascript

我的网站上遇到了资源链接问题

举个例子：

站点地址（示例）： www.abc.com/abc/xyx

正在加载的源 ： www.abc.com/abc/style.css

链接到我的网站

这是 css 和 js 的加载路径错误。

这是 .htaccess 文件

# 1.To use URL Alias you need to be running apache with mod_rewrite enabled. 
# 2. In your opencart directory rename htaccess.txt to .htaccess.
# For any support issues please visit: http://www.opencart.com

# If your opencart installation does not run on the main web folder make sure you folder
it does     run in ie. / becomes /shop/ 
RewriteBase /
RewriteRule ^sitemap.xml$ index.php?route=feed/google_sitemap [L]
RewriteRule ^googlebase.xml$ index.php?route=feed/google_base [L]
RewriteRule ^download/(.*) /index.php?route=error/not_found [L]

RewriteCond %{REQUEST_FILENAME} !-d

RewriteRule ^([^?]*) index.php?_route_=$1 [L,QSA]

我不知道为什么会错。我建立在Opencart上。
