However after a few other upgrades i.e. Apache2 and a few others, now the buttons do not appear on my machines, inside my intranet. I have been told, and have seen myself, that they do appear when the pages are viewed from outside my internal network
So, what's the difference between inside & outside? Does it use different domains? Are you including images from sites out there unreachable from the intranet? Is your server configured to reject the buttons to internal users?
