What’s inside the file below?

include snippets/fastcgi-php.conf;

Also, just a quick restructure of your server block, just to keep things a little more organized and add a bit that’s missing.

server {
    listen 80;
    servername lazerusdesigns.com www.lazerusdesigns.com;

    root /var/www/lazerusdesigns;

    accesslog /var/log/nginx/www.lazerusdesigns.com.access.log;
    errorlog /var/log/nginx/www.lazerusdesigns.com.error.log;

    location ~.php$ {
        include snippets/fastcgi-php.conf;
        fastcgipass 127.0.0.1:9000;
        fastcgiparam SCRIPTFILENAME $documentroot$fastcgiscriptname;
        include fastcgiparams;
    }
}

@jlazerus

In the new server block I provided, replace:

    location ~.php$ {
        include snippets/fastcgi-php.conf;
        fastcgipass 127.0.0.1:9000;
        fastcgiparam SCRIPTFILENAME $documentroot$fastcgiscriptname;
        include fastcgiparams;
    }

… with (i.e use only my configuration, none of the custom configuration you have right now):

    location ~ [^/]\.php(/|$) {
        fastcgi_split_path_info ^(.+?\.php)(/.*)$;
        fastcgi_pass   127.0.0.1:9000;
        fastcgi_index  index.php;

        include fastcgi_params;
    }

If you want to change /etc/nginx/fastcgi_params, you can make a backup:

cp /etc/nginx/fastcgi_params /usr/local/src/fastcgi_params

Remove it:

rm -rf /etc/nginx/fastcgi_params

And then create a new one:

nano /etc/nginx/fastcgi_params

… and paste in:

    fastcgi_param  SCRIPT_FILENAME    $request_filename;

    fastcgi_connect_timeout 60;
    fastcgi_send_timeout 180;
    fastcgi_read_timeout 180;
    fastcgi_buffer_size 512k;
    fastcgi_buffers 512 16k;
    fastcgi_busy_buffers_size 1m;
    fastcgi_temp_file_write_size 4m;
    fastcgi_max_temp_file_size 4m;
    fastcgi_intercept_errors off;

    fastcgi_param  PATH_INFO          $fastcgi_path_info;
    fastcgi_param  PATH_TRANSLATED    $document_root$fastcgi_path_info;

    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  REQUEST_SCHEME     $scheme;
    fastcgi_param  HTTPS              $https if_not_empty;
    fastcgi_param  HTTP_PROXY         "";

    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;

You’d then reload NGINX:

systemctl reload nginx

or

service nginx reload

The above is, of course, assuming you have PHP-FPM setup to use TCP instead of the default socket.

To check this, you’d need to change to your PHP-FPM directory:

cd /etc/php/*/fpm/pool.d

The above should put you in the correct directory. You’d then edit the file inside and look for the listen directive and make sure it’s set to 127.0.0.1:9000.

So I made the changes you suggested but now I’m getting a 403 Forbidden. My other website is still up though so that’s good.

This is the error.log now.

If I add index index.php; to my server block, I get a 502 error again.

Its fixed. I had to edit my php.ini and change the value of cgi.fix_pathinfo from 0 to 1.
