Page not loading in IE

I just made some CSS changes to a page and all works perfect in firefox safari, chrome but when i view it in IE there is nothing. I mean just a blank开发者_高级运维 page

Also this is a miva site

try validating your html. You also don't have an end title tag.

Close title tag.

It looks like the tag in the page head isn't closed properly (line 4). FF and Chrome often fix this sort of error for you as they render the page, IE isn't on this occasion.
