What are the nginx rewrite rules for sitemap support?

Whoops. I wish I had a way to figure out when there are replies to my questions 🙂

So here is one of the sites that does not ‘work’: https://betatechnologies.info/

And these are the nginx rules I’ve got (the site is running W3 Total Cache and is behind CloudFlare), which are for a multisite instalation:

index index.php;

include /var/www/betatechnologies.info/web/nginx.conf;

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

       # Add trailing slash to */wp-admin requests.
       rewrite /wp-admin$ $scheme://$host$uri/ permanent;

# for multisite with directories
if (!-e $request_filename) {
rewrite /wp-admin$ $scheme://$host$uri/ permanent;
rewrite ^/[_0-9a-zA-Z-]+(/wp-.*) $1 last;
rewrite ^/[_0-9a-zA-Z-]+(/.*\.php)$ $1 last;
}

# try this if direct access fails; it's slower; but W3TC ought to add expiry headers
rewrite ^.*/files/(.*) /wp-includes/ms-files.php?file=$1;

location ~ ^/files/(.*)$ {
        try_files /wp-content/blogs.dir/$blogid/$uri /wp-content/blogs.dir/$blogid/files/$uri /wp-includes/ms-files.php?file=$1 ;
        # access_log on; log_not_found on; expires max;
}

       # Directives to send expires headers and turn off 404 error logging.
location ~* ^.+\.(xml|ogg|ogv|svg|svgz|eot|otf|woff|mp4|ttf|css|rss|atom|js|jpg|jpeg|gif|png|ico|zip|tgz|gz|rar|bz2|doc|xls|exe|ppt|tar|mid|midi|wav|bmp|rtf)$ {
       access_log off; log_not_found off; expires max;
}

# Deny access to any files with a .php extension in the uploads directory
# Works in sub-directory installs and also in multisite network
# Keep logging the requests to parse later (or to pass to firewall utilities such as fail2ban)
location ~* /(?:uploads|files)/.*\.php$ {
        deny all;
}

#avoid php readfile()
location ^~ /blogs.dir {
        internal;
        alias /var/www/betatechnologies.info/web/wp-content/blogs.dir ;
        access_log off; log_not_found off;      expires max;
}
