https Pages Return Error

I just moved our website to a new server. I setup the ssl certificate and now whenever I visit an https page like the checkout page I get the following error. "an error occurred while processing this directive"

I am wondering if I didn't transfer the ssl certificate correctly, though my hosting provider said it looks fine.

The website is at http://www.keystonepetplace.com

Resolved. It is not possible to transfer a bluehost ssl to another server.
