'Older Posts' link error

Hi. Thank you for the lovely Fotographie wordpress theme. It's just what the blogger ordered. Just one issue here, really. The 'older posts' link is not working. I even tried to install Jetpack to get 'infinite scroll' working but even that didn't work. WHen i clicked on 'older posts', the box would disappear, but the page would not scroll anymore at all. Could you please let me know what's wrong here. My domain is: zahidjavali.com. Thank you in advance. Z
