Hey @flature,

I checked your site in Internet Explorer and everything is working fine.

Please clear Internet Explorer’s cache or history and check again.

If you’re using IE 10 and below, regretfully, we could not support old versions of Internet Explorer as they are no longer officially maintained.

Thanks.
