Plug In (Sociable)

I am using the sociable plug in. When I do a blog entry and click on preview, all the sociable buttons appear. However, they are not visible on my site posts. What the heck? I can’t make heads or tails of why this is happening. Not only that, but they used to appear, and now they don’t appear in any of the ones they used to appear on. It seems it’s everytime I update either my plug in or website I have a problem, but not sure if that’s true, or coincidental. Please someone help.
