The Share module was disabled due to a conflict with the Share button and Facebook's own Javascript libraries. For more information, see:

If you want to manually insert the share button into an article, or other page, you can by using the { JFBCShare} tag (no spaces). If you test out the tag, or want the module specifically to test, we can PM it to you. However, enabling the share button on many sites was causing other modules or the Login Using Facebook button to disappear.
With the 3.1 release, we'll be adding features to make the JFBCLike button more share-like, according to Facebook's newest recommendations. Those recommendations include not using the Share button anymore.
Hope this helps!
