Your config is wrong. The root directive is defined in location / will be never applied to location ~ \.php$. So when you hardcoded SCRIPT_FILENAME in PHP location without define root directive, the SCRIPT_FILENAME becomes URI.

This can be solve by move the root directive to the server level context and use $document_root when defining SCRIPT_FILENAME instead of hardcoded:

server { listen 80; server_name im; access_log /var/www/website/access.log; error_log /var/www/website/error.log; root /var/www/website; location ~ \.php$ { fastcgi_pass 127.0.0.1:9000; fastcgi_index index.php; fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name; include /etc/nginx/fastcgi_params; } } 

it get a "Oops! This link appears to be broken." error in CHROME.

Chrome shows its own error page if the error page is less than 512 bytes.

I suspect that you have the following line in fastcgi_params:

fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name; 

and if so, because the root directive is defined in location / will be never applied to location ~ \.php$, thus the SCRIPT_FILENAME becomes URI.

This can be solve by moving the root directive to the server level context:

server { listen 80; server_name im; access_log /var/www/website/access.log; error_log /var/www/website/error.log; root /var/www/website; location ~ \.php$ { fastcgi_pass 127.0.0.1:9000; fastcgi_index index.php; fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name; include fastcgi_params; } }
