A Magazine Theme Vast Sea Of White

Hey there.

I'm running the BP Magazine theme and I can't for the life of me get the custom theme to work. Every time I select it, all I get is a white background / lack of CSS styling. While the other features pass through, like the posts in the featured slider window and custom text, nothing selected color-wise or background-wise transfer.

What have I selected wrongly?

Oh! I should note that I've tried both the main and the daughter versions of the theme.
