    Are you using centmin.sh menu option 22 Wordpress installer with Cache Enabler caching option selected or have used it in the past but disabled it later? That variable is part of cache enabler's mapped args variables at /usr/local/nginx/conf/wpcacheenabler_map.conf include file which is referenced in /usr/local/nginx/conf/nginx.conf
    Code (Text):
    map $http_user_agent $cmwpcache_device {
    default                                     'desktop';
    ~*(iPad|iPhone|Android|IEMobile|Blackberry) 'mobile';
    "~*Firefox.*Mobile"                         'mobile';
    "~*ipod.*mobile"                            'mobile';
    "~*Opera\ Mini"                             'mobile';
    "~*Opera\ Mobile"                           'mobile';
    "~*Mobile"                                  'mobile';
    "~*Tablet"                                  'mobile';
    "~*Kindle"                                  'mobile';
    "~*Windows\ Phone"                          'mobile';
}

map $args $q_ignorearg {
  default               0;
  "~*fbclid"            1;
  "~*gclid"             1;
  "~*utm"               1;
  "~*fb_action_ids"     1;
  "~*fb_action_types"   1;
  "~*fb_source"         1;
  "~*age-verified"      1;
  "~*ao_noptimize"      1;
  "~*usqp"              1;
  "~*cn-reloaded"       1;
  "~*_ga"               1;
  "~*_ke"               1;
  "~*mc_cid"            1;
  "~*mc_eid"            1;
  "~*ref"               1;
}

    and then is usually referenced in your nginx vhost's include file for /usr/local/nginx/conf/wpincludes/yourdomain.com/wpcacheenabler_yourdomain.com.conf
    Code (Text):
        # include query strings fbclid, gclid, utm in cache via stripping them with
    # 302 redirect via mapping in /usr/local/nginx/conf/wpcacheenabler_map.conf
    if ($q_ignorearg) {
      set $check_qurl $request_uri;
      set $check_surl $request_uri;
      set $cache_uri $uri;
      #rewrite ^ $uri? redirect;
    }

    The error you have is most likely due to the include file /usr/local/nginx/conf/wpcacheenabler_map.conf not being enabled in /usr/local/nginx/conf/nginx.conf and your nginx vhost or include file at /usr/local/nginx/conf/wpincludes/yourdomain.com/wpcacheenabler_yourdomain.com.conf is referencing $q_ignorearg variable but it isn't finding it it declared in include file /usr/local/nginx/conf/wpcacheenabler_map.conf as it maybe commented out with a hash # in front or something is disabled
    Code (Text):
    grep -C1 wpcacheenabler_map.conf /usr/local/nginx/conf/nginx.conf
include /usr/local/nginx/conf/redisupstream.conf;
include /usr/local/nginx/conf/wpcacheenabler_map.conf;
include /usr/local/nginx/conf/lua-package-path-include.conf;

    also noticed i don't have this file: /etc/init.d/nginx

    I use for all website the option 1) Keycdn cache enabler. So it should not be disabled

    If you're using Centmin Mod 130.00beta01, it has now switched form init.d/nginx service to systemd native service file for fresh installs with SWITCH_NGINX_SYSTEMD='y' variable enabled by default

    Thank you for your replies.

    I added this 3 lines at /usr/local/nginx/conf/nginx.conf

    include /usr/local/nginx/conf/redisupstream.conf;
    include /usr/local/nginx/conf/wpcacheenabler_map.conf;
    include /usr/local/nginx/conf/lua-package-path-include.conf;

    i get now the error:

    Code:
    [16:16][root@CentOS-79-64-minimal autoprotect]# nginx -t
nginx: the configuration file /usr/local/nginx/conf/nginx.conf syntax is ok
nginx: [emerg] zero size shared memory zone "xwprpc"
nginx: configuration file /usr/local/nginx/conf/nginx.conf test failed

    by comparing with a healthy nginx config file , i saw that one line was missing,
    this one:
    limit_req_zone $binary_remote_addr zone=xwprpc:10m rate=30r/s;

    now nginx is running

    You may not need to add all 3 lines
    Code (Text):
    include /usr/local/nginx/conf/redisupstream.conf;
include /usr/local/nginx/conf/wpcacheenabler_map.conf;
include /usr/local/nginx/conf/lua-package-path-include.conf;

    the top and bottom ones are only added conditionally/dynamically by Centmin Mod if you use Redis based Nginx caching for Wordpress via centmin.sh menu option 22 as well and bottom if you use Nginx Lua.

    Now nginx is running but websites are still not reachable. PHP-fpm is also working and firewall is disabled. Not sure what to check now.

    If you disable CSF Firewall, then ports aren't usually opened by default. Re-enable CSF Firewall so the proper ports are opened.

    And THIS boys and girls is why I do, and will continue to, recommend CentMin either on CentOS 7 or the newer "stuff" to anyone that is willing to listen.
    If I had a few spare 10K in cash, I'd gladly send it to @eva2000, but I remain a simple civil servant that retired on a very limited retirement... but I DO encourage anyone that can - send money!
