Okay this seems like to me you have some sort of hack conflict in
VB if it works
I have viewed many vbulletin sites with reviewpost I know of and can not find any issue here

Even on your site the html is there in your page source of IE it just doesnt view. So if you switch stylesheets in
VB does it show in IE? Gotta be something with your
vb style or a hack here that is conflicting with Internet Explorer
