I have Dreamhost and when I asked them about the problem, they explained that it was because I had extra web secruity turned on when I created the domain. (It's on by default, so you'd have to turn it off when you create the folder or change it later.) They disabled it and tested the site and it works now. The extra secruity closes off a lot of PHP functions to prevent any type of hacker activity, but ends up creating a lot of problems too.
