Facebook share button not showing up I have installed the Facebook Share 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?
I was finally able to resolve the problem. Just posting the solution in case it comes useful to anyone else. 

As it turned out, the problem with Facebook share was display suite. The nodes that it was not working for were, of course, not random as it initially looked. They were the nodes which were using display suite. I didn't manage to find a solution to it and therefore I used the service links module (proposed by @Kenny Wyland), which had an extra feature covering the case that display suite is being used.
