问wordpress的页面突然无法登陆？

今天在服务器上搞了一会ftp，然后再去登陆自己的站点时发现进不去了，过了会页面显示nginx的错误页面，显示：

Something has triggered an error on your website. This is the default error page for nginx that is distributed with Fedora. It is located /usr/share/nginx/html/50x.html

You should customize this error page for your own site or edit the error_page directive in the nginx configuration file /etc/nginx/nginx.conf.
