[support] Blank page

I am going crazy here. I can not see my site. I am on Bluehost and I know they had some problems last week, which did not affect this one domain BUT I try to log in to my site and get a blank page. I called Bluehost and they suggested clearing the browser cache, which seemed to work up to a point. But now I see the public site but when I try to login as admin I again see just a blank page. I did not change the .htaccess file. Any ideas why I am getting (sometimes I get a 500 error) a blank page? This is the same across IE, Chrome and FF.
