我即将在我的虚拟机（Debian Jessie，ISPconfig 3.1）上设置 Mediawiki，访问网站时出现错误 500。这是我的 apache2 错误日志：
[fastcgi:error] [pid 8066] (2)No such file or directory: [client
51.15.70.216:56974] FastCGI: failed to connect to server
"/var/www/clients/client1/web10/cgi-bin/hhvm-fcgi-[IP-address]-
mydomain.com": connect() failed
[fastcgi:error] [pid 8066] [client 51.15.70.216:56974] FastCGI:
incomplete headers (0 bytes) received from server
"/var/www/clients/client1/web10/cgi-bin/hhvm-fcgi-[IP-address]-80-
mydomain.com"
网络文件夹的所有权限都设置好了，有人可以告诉我我能做些什么来让我的配置正常工作吗？
谢谢！
