I have just upgraded my plan from Premium to Business and all sorts of weird stuff has happened. Firstly, all the Category Post widgets and the free HTML on the Magazine front page were removed – yielding a blank page. This I fixed quite quickly by setting the page up again. The problem I have is that the Widgets are not working the way they did before.
The specific issue is that Category Post Boxed and Category Post Grid widgets are displaying sharing buttons below the featured post in the Boxed widget and below all the posts in the Boxed widget. Your example site does not do this and my site prior to the upgrade did not either.
I don’t want this to happen, but can find no explanations as to why it is happening or of how to get rid of the sharing buttons.
