I have nginx setup on my ubuntu server as the web server with 3 config files (minus the site configs)All of my sites now download a application/octet-stream file rather than serving up the pages.Where am I going wrong, and how can I get it back to serving the pages up?nginx.confuser www-data; worker_processes 8; pid /run/nginx.pid; events {    worker_connections 2048;}http {    sendfile on;    tcp_nopush on;    tcp_nodelay on;    keepalive_timeout 10;    types_hash_max_size 2048;    server_tokens off;    fastcgi_read_timeout 3600;    include /etc/nginx/mime.types;    default_type application/octet-stream;    access_log /var/www/log/access.log;    error_log /var/www/log/error.log;    ignore_invalid_headers on;    client_max_body_size 1024M;    client_body_buffer_size 15m;    client_header_timeout 400;    client_body_timeout 400;    send_timeout 400;    connection_pool_size 256;    client_header_buffer_size 4k;    large_client_header_buffers 4 32k;    request_pool_size 4k;    output_buffers 4 32k;    postpone_output 1460;    open_file_cache max=10000 inactive=20s;    open_file_cache_valid 30s;    open_file_cache_min_uses 2;    open_file_cache_errors on;    map $scheme $fastcgi_https {        default off;        https on;    }    ssl_session_cache shared:SSL:10m;    ssl_session_timeout 10m;    ssl_ciphers  HIGH:!aNULL:!MD5;    ssl_prefer_server_ciphers on;    fastcgi_cache_path /etc/nginx/cache levels=1:2 keys_zone=MYAPP:100m inactive=60m;    fastcgi_cache_key $scheme$request_method$host$request_uri;    include /etc/nginx/conf.d/*.conf;    include /var/www/site-config/*;}conf.d/gzip.confgzip on;gzip_disable msie6;gzip_vary on;gzip_proxied any;gzip_comp_level 9;gzip_buffers 16 32k;gzip_min_length 50;gzip_types    text/css    text/plain    text/javascript    application/javascript    application/json    application/x-javascript    application/xml    application/xml+rss    application/xhtml+xml    application/x-font-ttf    application/x-font-opentype    application/vnd.ms-fontobject    image/svg+xml    image/x-icon    application/rss+xml    application/atom_xml;conf.d/all-sites.confserver {    listen 80;    listen 443 ssl;    location ~ /\. {        deny all;    }    location = /50x.html {        root /usr/share/nginx/html;    }    location / {        server_tokens off;        client_max_body_size 20m;        client_body_buffer_size 128k;        try_files $uri $uri/ /index.php?q=$uri&$args;    }    location ~ [^/]\.php(/|$) {        set $no_cache ;        if ($request_method !~ ^(GET|HEAD)$) {            set $no_cache 1;        }        if ($no_cache = 1) {            add_header Set-Cookie _mcnc=1; Max-Age=2; Path=/;            add_header X-Microcachable 0;        }        if ($http_cookie ~* _mcnc) {            set $no_cache 1;        }        add_header X-Powered-By Kevin Pirnie;        fastcgi_no_cache $no_cache;        fastcgi_cache_bypass $no_cache;        fastcgi_cache MYAPP;        fastcgi_cache_valid 200 60m;        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;        include fastcgi_params;        fastcgi_buffer_size 128k;        fastcgi_buffers 256 4k;        fastcgi_busy_buffers_size 256k;        fastcgi_temp_file_write_size 256k;    }    location ~* \.(?:manifest|appcache|html?|xml|json)$ {        add_header X-Powered-By Kevin Pirnie;        expires -1;    }    location ~* \.(?:rss|atom)$ {        if ($http_cookie ~* _mcnc) {            add_header X-Powered-By Kevin Pirnie;            expires 1h;            gzip on;            add_header Pragma public;            add_header Cache-Control public, must-revalidate, proxy-revalidate;        }    }    location ~* \.(?:jpg|jpeg|gif|png|ico|cur|gz|svg|svgz|mp4|ogg|ogv|webm|htc|otf|ttf|eot|svg|woff)$ {        if ($http_cookie ~* _mcnc) {            add_header X-Powered-By Kevin Pirnie;            expires 1y;            access_log off;            gzip on;            add_header Pragma public;            add_header Cache-Control public, must-revalidate, proxy-revalidate;        }    }    location ~* \.(?:css|js)$ {        if ($http_cookie ~* _mcnc) {            add_header X-Powered-By Kevin Pirnie;            expires 1y;            access_log off;            gzip on;            add_header Pragma public;            add_header Cache-Control public, must-revalidate, proxy-revalidate;        }    }}/var/www/site-config/sampleserver {    server_name  www.thisismysite.com;    return       301 http://thisismysite.com$request_uri;}server {    root /var/www/httpdocs/thisismysite.com;    index index.php;    server_name thisismysite.com;   }
