White Site after Ubuntu and PHP Update - php

Question

i have a Problem. My Website is only a White Clean Site. With no Error, like nothing there.
Running Ubuntu 16.04, NGINX and PHP5.6-fpm
/var/run/php/php5.6-fpm.sock is exists.
The Site is running before with my NGINX Settings, here is PHP location
location ~ \.php$ {
#NOTE: You should have "cgi.fix_pathinfo = 0;" in php.ini
try_files $uri =404;
include fastcgi_params;
fastcgi_intercept_errors on;
fastcgi_pass unix:/var/run/php/php5.6-fpm.sock;
}
Before (Ubuntu 14.04 and PHP5-fpm) it was fastcgi_pass unix:/var/run/php/php5-fpm.sock;
But i cannot install php5-fpm anymore, cause Ubuntu 16.04 doesnt support it.
If i take a look to /var/log/nginx/error.log there is nothing! No Logs from the Site
I dont know what i can do... i tried php7.0 but also same look...
