Have had a response from them already.

I have tested a stock 4.4.1 Gold installation, the login error message
appears in the right top corner (please have a look at the screen shot
attached).

The problem may be caused by custom design modifications or custom skin
integrated to your 4.4.1 sites. Feel free to create a support request in
your personal Helpdesk account. Our support engineer will help you to sort
this issue out.

So it appears it is fine on a stock install.

Unforunately we have no way of checking this under https

Is anyone else having the same problem? We are running two sites, both have the exact same issue.

Thanks
