Screwed up Nginx with yum update to 1.8.0

Hello. I did a “yum update” on my DO droplet with Linux. Now I have Nginx 1.8.0, but now my config doesn’t work for some reason. It gives me an error while starting up:

Feb 09 09:52:37 servername systemd[1]: Starting The nginx HTTP and reverse proxy server… 
*Feb 09 09:52:37 servername nginx[27173]: nginx: [alert] version 1.6.3 of nginx.pm is required, but 1.8.0 was found 
*Feb 09 09:52:37 servername nginx[27173]: nginx: configuration file /etc/nginx/nginx.conf test failed 

Any ideas how to fix this? I tried the options mentioned here - http://serverfault.com/questions/690265/nginx-1-6-3-to-1-8-upgrade - but they don’t work. Here’s my nginx.conf:

location ~ \.php$ {

	try_files $uri =404;
	fastcgi_index index.php;
	
	#include fastcgi_params;
	include fastcgi.conf;

	#This is the first line inside fastcgi.conf
	#fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;

	#fastcgi_pass unix:/var/run/php-fpm/php-fpm.sock;
	fastcgi_pass 127.0.0.1:9000;
              
}

Just FYI:

1. I tried fastcgi_pass with the unix sock thing, instead of the 127.0.0.1:9000 bit. Both give the same error.

2. Here’s my full fastcgi.conf file:

fastcgi_param  SCRIPT_FILENAME    $document_root$fastcgi_script_name;
fastcgi_param  QUERY_STRING       $query_string;
fastcgi_param  REQUEST_METHOD     $request_method;
fastcgi_param  CONTENT_TYPE       $content_type;
fastcgi_param  CONTENT_LENGTH     $content_length;

fastcgi_param  SCRIPT_NAME        $fastcgi_script_name;
fastcgi_param  REQUEST_URI        $request_uri;
fastcgi_param  DOCUMENT_URI       $document_uri;
fastcgi_param  DOCUMENT_ROOT      $document_root;
fastcgi_param  SERVER_PROTOCOL    $server_protocol;
fastcgi_param  HTTPS              $https if_not_empty;

fastcgi_param  GATEWAY_INTERFACE  CGI/1.1;
fastcgi_param  SERVER_SOFTWARE    nginx/$nginx_version;

fastcgi_param  REMOTE_ADDR        $remote_addr;
fastcgi_param  REMOTE_PORT        $remote_port;
fastcgi_param  SERVER_ADDR        $server_addr;
fastcgi_param  SERVER_PORT        $server_port;
fastcgi_param  SERVER_NAME        $server_name;

fastcgi_param  REDIRECT_STATUS    200;
