Cant See Main Content Post/Text

I have one reader who reports that they can’t see my main content text. They can see the images contained within the posts however. The can also see the sidebars and links. Just not the posts. She reports trying several browsers and is experiencing the same thing in Firefox and IE. I am just sort of looking for some ideas people might have on what could be wrong on her end. As far as I know, no one else is having the same problem. I’m certaintly not. Still working on getting her exact browser versions. I apologize in advance if this isn’t the best place to pose this question.
