mobile site main menu is not showing

Hi, I have nasilgreencardaldim.com as my blog. I just got installed the adsense for the first time but apparently I messed up with couple of features. The most important one, is the mobile site's main navigation menu. When a user clicks to menu on the top left side, nothing comes up. It is completely blank, while desktop version has the menu as it should. Can you help me fixing it? Thanks!
