Nginx restart fails during LEMP setup, help?

Hi all!

When I I try to restart nginx, after editing sudo nano /etc/nginx/sites-available/default, I get this fail response:

Restarting nginx nginx [fail]

Checking the error.log I get this:

2014/09/22 14:50:48 [emerg] 5568#0: invalid variable name in /etc/nginx/sites-enabled/default:56

I assume this means that the issue is line 56 on the “default” file.

If that’s the case, then the issue is supposedly:

fastcgi_split_path_info ^(.+\.php)(/.+)$;

Which, according to this tutorial (https://www.digitalocean.com/community/tutorials/how-to-install-linux-nginx-mysql-php-lemp-stack-on-ubuntu-14-04), is exactly as it should be.

So what am I doing wrong and how can I fix it?

Thanks in advance.
