How do I add rate widget to certain content type? I have a certain content type I want users to be able to rate. I decided to go with the rate module, since I want to be able to change the value of each star.

My problem is I don't know how to add the certain rate widget to a content type. In widget settings there are no checkboxes in the "Node types" option. Screenshot below.
I cannot find a clear reason for why this happened. The best answer I can give to someone with the same problem (doesn't seem to be a common problem at all) is to start over with a clean Drupal install.
