can't create new posts if I'm signed in?

Have tried to create a new post in various subs on here and there is no START A DISCUSSION button?!

Google searched why there was no option and found a thread that linked to Community Natter and oddly THAT forum has the option available!

Then I checked what happened if I logged out and bizarrely the button appears! (see below)

tried dumping cookies for Virgin site, but that hasn't solved my START A DISCUSSION issue.

All i wanted to do was post to discuss why I keep getting intermittent drops out that appear to be Google DNS related and not router outages.... {sigh}

Anyone got a Discussion Starter solution?

TIA
