Blog is not properly visible on IE

I had the version 2.8 and iNova THEME has been applied prior. I was doing some changes in styles.css file to get a image in the header. Suddenly I found the calendar, blogroll, theme etc in the right side has been disappeared.

Not able to solve the problem. So I upgrade the version to word press 2.0 and upload again iNova THEME into the site. Also I have uploaded the elegant-Box THEME. Still no luck.

Every thing is looks fine in Firefox, but not appeared in IE. I have checked IE 6.0 and 8.0 as well from different locations.

The BLOG url is https://sharepointhimadrish.com/.

Please advise.
