# deny access to .htaccess files, if Apache's document root
# concurs with nginx's one

location ~ /\.ht {
    deny all;
}

In your virtual Host file located @ /etc/nginx/sites-available/yourdomain.com

FIND AND ADD : DOMAIN.com www.DOMAIN.com *.DOMAIN.com; to server name

 root /var/www/egaffar.com/datazone;
    index index.php index.html index.htm;
    # Make site accessible from http://localhost/
    server_name DOMAIN.com www.DOMAIN.com *.DOMAIN.com;

    location / {
        # First attempt to serve request as file, then

Then type the below command

nginx -t && service nginx restart
