I have installed the [Facebook Share](http://drupal.org/project/facebookshare) module on my Drupal 7 site and configured it accordignly to my preferences but it is not showing up on any of the pages I chose.

I just tested it even further by choosing it to be displayed every (full) node and it is showing up on basic pages, faq, and some more but not on my Ubercart products and one custom content type. It does show up on another custom content type.

Any ideas?
