Google + Activities not showing

Hi Super Devs,

I can't get imported posts to Show in my Google + Page widget.

I have created a Project in the Google Developers Console, Authorised and tested it. I receive a message stating: "Google+ List of Activities for Collection PUBLIC successfuly reached" (please note the spelling mistake in "successfully" that the plugin produces)

However, nothing appears and the page I am trying to display does have public posts:

Kind regards,
