Since in my first post I had used the phrase, "replace the
one on your site with it". I'll be more clearer.

Looking at your temporary site. The styles directory doesn't have the
ps3yt-min.css file in it.

Download the original ps3yt-min.css file and put it in the styles directory
and see if that fixes the problem.
