After updating Sociable social bookmarking plugin for WordPress. I notice Sociable was gone for some of my post.
I need to go back to edit some of my posts to uncheck the Sociable disabled checkbox on the editing page.
 I recommend enabling sociable on the frontpage. The posts that d0 not have the sociable icons need to be fixed.
Update in later versions: The problem seems to be fixed, and I don’t experience this problem anymore.
