Site Not Showing Up

[Brookreed]

I spent the evening installing the MAS, which I've done successfully in the past. However, when I try to access the site after installation, nothing shows up, on any page of the site--just a blank white page. I tried one of my old sites as well, and I noticed it was doing the same thing, though with a slightly older version of the script whereas this is the most current version. I'm using x10hosting, does anyone know what the problem is and how to fix it? I've tried switching browsers and have looked for other threads on the forum, but I can't seem to find anything to fix the problem. Thank you for your time.
