hompepage side bar not showing up in IE

Hi
I am sort of a newbie at wordpress. I am helping someone figure this out and couldnt find the problem in the code my self. on https://www.marcgopin.com the side bar doesnt show up on the homepage in IE. on every other page it is there, but not on the homepage.

is there a reason for this? the snippet of code is in place –

/<?php get_sidebar();?> /

but its not coming up.

any help would be great

thanks
