Found the issue (i think).

What I did was only restarting php-fpm, nginx and ajenti using 'service xxx restart' command.

when i do complete stop of php-fpm & nginx using 'service xxx stop' and login to ajenti panel, click on restart ajenti followed by restarting the websites this fixed the issue. seems weird though but at least it fixed it.

thanks eugene for the review.
