This widget makes a remote call to the Facebook server, sometimes it does not show (appears blank) when you check it in the builtin web preview. Correctly implemented widgets should show when the page is published.

Note:
You have to allow subscriptions in your Facebook profiles account settings. Click on the 'Subscribers' link on the menu on the left side of the screen, and check the box on "Allow subscribers". That should enable the follow plugin to work for your profile.
