Site shows distorted in IE, but ok on Firefox

I am using the Blix theme on https://theseobible.com

The site seems ok on Firefox, but the sidebar and home links etc. show up in different places, and the formatting is off.

I have only added a form for subscription of feed on the sidebar.php in the blix theme.

Any suggestions as to what could be wrong with displaying in IE.

Is this an issue with the Blix theme or anything else?

Please advice.

Thanks,
Vinai
