 @riasat Just focusing on your error here, rather than the ticket - Looks
 like you've got a error in your nginx config there, although that should
 work for matching (and appears to be), the matched name isn't be passed to
 PHP, instead it's passing the literal regex through.
 You need to correct the value being passed to PHP through `fastcgi_param
 SERVER_NAME ...` in your nginx config, something like
 http://serverfault.com/questions/650560/nginx-regex-vhost-pattern-ends-up-
 as-php-server-name should set your on your way.
