kustodian,

Thank You for your fast reply, i have resolved this by editing one of my 'location' in my nginx.conf file:
..............
location / {
root /var/www/html;
index index.php index.html index.htm;
fastcgi_param REDIRECT_STATUS 200;
}
.....................
Previously this was '/usr/share/nginx/html', but it was 'var/www/html' in all other 'location's.
