Short Code don’t run

Hi,
I prefer your plugin because it use a short URL for messages.
I have installed the free version using short code into widget, and I wont show whatapp icon in the following page:
http://infocity.website/lugaresdeinteres/
It is not a page… it is an archive page (I can modifier it only addind widget…).
But whatsapp icon is not showed…
I have tested others whatsapp plugin that to use short code, and it runs.
Maybe I need premium version for show the icon in:
