Nginx and Frog CMS admin url

Question

Short background - there is a site (powered by Frog CMS) hosted on VPS with Apache installed. To cut costs a bit, I've moved to another VPS hosting with cheaper plan.

I've installed nginx, php-cgi and before moving production version, made a test version - "http://test-mysite.lv". It seemed to work fine except the admin part. When I enter this url "http://test-mysite.com/admin/" , browser is redirected to production site backend - "http://www.mysite.lv/admin/?/login". I don't have any idea , why I get redirected.

I configured this virtual host like this :

server {
  listen       80;
  server_name  www.test-mysite.lv test-mysite.lv;

  location / {
               root        /var/www/vhosts/test-mysite.lv;
               index           index.php index.html;
            }

  error_page  404              /index.html;

  # redirect server error pages to the static page /50x.html
  error_page   500 502 503 504  /50x.html;
  location = /50x.html {
      root   share/nginx/html;
  }

  location ~.*\.php$ {
      #root           html;
      fastcgi_pass   127.0.0.1:9000;
      fastcgi_index  index.php;
      fastcgi_param  SCRIPT_FILENAME  /var/www/vhosts/test-mysite.lv$fastcgi_script_name;
      #fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
      include        fastcgi_params;
  }

  location ~ /\.ht {
     deny  all;
  }
}

Site root permissions :

Any help would be appreciated.

Answer 1

The problem wasn't in nginx config, it was my CMS configuration.

In config.php, I changed define('URL_PUBLIC', 'http://mysite.lv'); to define('URL_PUBLIC', 'http://test-mysite.lv'); and it worked.
