Hi everyone,

Just chasing up below, if anyone has any suggestions?

So to recap, the situation is, I have nginx running Wordpress with the
Hypercache plugin but only the homepage is cached, other pages "miss"
according to page headers.

Here is contents of the sites-enabled conf in question:


server {
        listen 80;
        listen 443 ssl http2;

        server_name NAMEOFSITECHANGED.COM;

        ssl_certificate /etc/nginx/ssl/NAMEOFSITECHANGED.COM.crt;
        ssl_certificate_key /etc/nginx/ssl/NAMEOFSITECHANGED.COM.key;
        keepalive_timeout 70;

        #enables all versions of TLS, but not SSLv2 or 3 which are crap
and now deprecated.
        ssl_protocols TLSv1 TLSv1.1 TLSv1.2;

        #disable weak ciphers
        ssl_ciphers

        if ($http_cookie ~*

{ set $skip_cache 1; }


        #main
        location / {

            index index.htm index.php;
            try_files $uri $uri/ /index.php?$args;
            error_page 404 = /404;

            #handle old permalink URLs and rewrite
            #rewrite ^/?video/(.*) /$1 permanent;
        }


        #pass the PHP scripts to FastCGI
        location ~ \.php$ {

            include snippets/fastcgi-php.conf;
            include fastcgi_params;

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

            expires max;
            add_header Pragma public;
            add_header Cache-Control "public, must-revalidate,
proxy-revalidate";
       }
}


And contents of /etc/nginx/nginx.conf:

user www-data;
worker_processes auto;

    worker_connections 8192;

    include /etc/nginx/conf.d/*.conf;
    include /etc/nginx/sites-enabled/*;
}



/etc/nginx/conf.d is empty.

Any ideas as to what I've messed up?

Thanks!
