Hello everybody, I'm out of ideas here. I updated my server to Ubuntu Xenial and PHP was updated to 7. php5 seems to be no longer installed. So I checked the perfect server tutorial and updated the PHP settings like this: However, I just get a Internal Server Error for sites handled by ISPConfig. The error log shows the following: Code: [Wed Jul 20 08:38:06.445803 2016] [fastcgi:error] [pid 2162] (2)No such file or directory: [client 2a02:2ad0:245::37:34092] FastCGI: failed to connect to server "/var/www/clients/client1/web1/cgi-bin/php5-fcgi-[2a01:4f8:xx:xxx::2]-80-mysite.de": connect() failed [Wed Jul 20 08:38:06.445897 2016] [fastcgi:error] [pid 2162] [client 2a02:2ad0:245::37:34092] FastCGI: incomplete headers (0 bytes) received from server "/var/www/clients/client1/web1/cgi-bin/php5-fcgi-[2a01:4f8:xxx:xxx::2]-80-mysite.de" The message itself is clear and the reason is comprehensible: The files really do not exist. But whats the reason here? The file path is referring to php5-fcgi. Wouldn't that be php7?
