Image Captions not Aligning Centrally

I’m using Inspiration WordPress theme.
I’ve added the align properties suggested by a few threads and added text-alight: centre to the caption properties in the CSS but to no avail.

Here’s the page:
http://www.rantages.com/blog/tweenagerfail/

The Image Captions should align as shown in
http://www.rantages.com/footyblog

But instead they are aligning left.

Here’s the style.css
