If you’ve recently upgraded your Sociable plugin to 3.5.2+, you’ll notice that the image icons on your single ad pages look out of whack like this:
To fix this, go into “Settings” => “Sociable” and check the “Disable sprite usage for images?” box. Save and everything should now be all fixed. If you are using WP Super Cache, you might need to clear the cache first. Also some browsers might need to clear their cache as well (ctrl+ reload page).
