Site Not Loading on IE11

Hi.

My site was working fine on all browsers, but it seems like it’s not loading at all on Internet Explorer 11 now.

There was an issue with the logo jumping up on top of the menu items so I added the code
.logo { z-index: 1; }
which fixed it. And then when I went to view the site again it wasn’t responding.

I deactivated the plugins, cleared cache, but still not loading.

Any ideas?

Thank you.
