Hello I have ampz on my site and at first i only was using Facebook and twitter which work fine, now i added instagram and the button does not appear, even changed the order so it comes first but it still does not show up. Tried deleting cache, different browsers and nothing.
You can check the live site here http://arteymedios.org/presentacion-barbara-gonzalez

Using ampz 2.1.8 on Joomla 3.6.5 and K2 2.7.1

Regards.
