WordPress从Apache迁移到Nginx后，永久链接的帖子空白

Background:

Server is Digital Ocean with Ubuntu 14.04.04 running Nginx
nginx version: nginx/1.10.1
mysql Ver 14.14 Distrib 5.6.33, for debian-linux-gnu (x86_64)
PHP 5.5.9-1ubuntu4.22 (cli) (built: Aug 4 2017 19:40:28)
URL of the Wordpress is DocoSacramento.com
Wordpress was migrated from an Apache server
Pages work great! (such as http://docosacramento.com/explore/dine/ or http://www.docosacramento.com/about/)
Issue: Posts show up as blank white pages when visited (such as http://www.docosacramento.com/blog/grandest-openings-punch-bowl-social/ or http://www.docosacramento.com/news/another-sales-milestone-residences-sawyer-penthouses-sold/)
The posts follow the permalink structure of "docosacramento.com/%category%/%postname%/" (refer to the following image for a visual) permalinks settings screenshot

My Nginx Server Block is currently as follows:

upstream php {
    server unix:/run/php-fpm/php-fpm.sock;
}

server {
    listen 80 default_server;
    listen [::]:80 default_server ipv6only=on;

    root /var/www/docosacramento.com/public_html;
    index index.php index.html index.htm;

    server_name docosacramento.com www.docosacramento.com;

    if (!-e $request_filename) {
            rewrite ^(.*)$ /index.php?q=$1 last;
    }

    location / {
            try_files $uri $uri/ /index.php?q=$uri&$args;
    }

    location /news {
            index index.php index.html index.htm;
            try_files $uri $uri /news/index.php?q=$uri&$args;
    }

    error_page 404 /404.html;

    error_page 500 502 503 504 /50x.html;
    location = /50x.html {
            root /usr/share/nginx/html;
    }

    location ~ \.php$ {
            try_files $uri =404;
            fastcgi_split_path_info ^(.+\.php)(/.+)$;
            fastcgi_pass unix:/var/run/php5-fpm.sock;
            fastcgi_index index.php;
            fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
            fastcgi_param PATH_TRANSLATED $document_root$fastcgi_script_name;
            include fastcgi_params;
            fastcgi_cache_key $host$request_method$request_uri;
    }
}

I'm guessing that perhaps location blocks are needed for each of the 4 post categories this website has (which are news, blog, gallery, and press-release) so I created a location /news {... block for testing but that does not seem to have made any changes when visiting posts that begin with /news/. Also, I've been sure to run the following commands each time I've edited the Nginx server block:

sudo nginx -t
sudo service nginx restart
sudo service php5-fpm restart

Is there anything else I can try or test? Are there any logs or additional information I can provide? Please let me know!

Update - Error messages from switching Wordpress debugging on, revised after debugging a few of the easy ones:
