child theme does not load parent css

Hi,
I recently redid my podcast’s site with the Parabola theme, and when I went to make a child theme so I could customize some templates I couldn’t get it to load the parent theme’s CSS. I put it on a test installation and it worked, so I’m not sure what’s causing this. I noticed when I changed it that my code had this:
<style id='parabolas-css' media='all'></style>
instead of this:
<style id='parabolas-css' media='all'>@import url(wp-content/themes/parabola/style.css) ;</style>

I’m running the latest versions of both WordPress and Parabola. Any ideas as to what could cause this?
