There is no update for the theme.
The creator rarely communicates with those who purchase his themes from mojo.
The only this is… it’s not just the featured image, no image will show up.
All I did after trying to go through all of these steps was….
Go to the plugin in your dashboard –> click Sociable Options –> then make sure that the box beside “Use the sociable stylesheet?” is checked… worked!
The only problem was… the colors were more dim – so now I need to go in & tweek those somehow in the stylesheet 😉
