There still appears to be something wrong with vbulletin-chrome.css....
This part in particular:
HTML Code:
.toplinks .nonotifications .popupbody a {
background:;
color:;
}
background and color seem to be empty when I look at the sheet. What you could try, is backup the contents of vbulletin-chrome.css and save them somewhere, and revert the template and see how it looks. I'm not too sure what is going on, but there is a CSS issue somewhere in one of the templates.
