Новая конфигурация для хостов nginx

Данные конфиги разрешают обращение только к index.php (и main.php для ЛК) в корнях админки и ЛК, запрещая доступ к любым другим php скриптам.

Данные переменные могут отличаться от ваших!
server_name, ssl_certificate, ssl_certificate_key,fastcgi_pass

Так же стоит понимать, что в данном примере ЛК использует 80 порт (http) а админка 443 (https).

В разделе http добавить:

log_format  post  '$remote_addr - $remote_user [$time_local] "$request" "$request_body"'
                      '$status $body_bytes_sent "$http_referer" '
                      '"$http_user_agent" "$http_x_forwarded_for"';
