Page Navigation not Working in Mobiles

Hi,

I am encountering a strange problem on My website is hacksecure.me

I am using a responsive theme by Elegant themes and have made lot of tweaks. Now the problem is that when I open my website in mobile browsers, the top menu which appears as ‘Pages Menu’ doesnt work on homepage but its working fine on any other page.
By working means when i click on it, it shows sub menu items. But on homepage it doesnt responds.
You will have to open the home page in mobile to identify the problem.

Please help.
