Wordpress post subject name in title (Rhianna theme)

 
Kernelreloaded uses Rihanna Wordpress theme by Kineda, and I really love it.
 
One thing I still didn't change from default is the was it displays posts. Currently no matter which page you are on title doesn't change, and if you bookmark it you will get only blog name not the post name in the title :(
 
I checked the source of the theme and found the culprit in header.php and the default code is:
title ?php bloginfo('name'); ? /title
 
Because of some protections you can't see full code on my blog, but check out examples at wordpress wp_title blog and how to change it.
