I get a "Login was unsuccessful!" message and a login form when I try to navigate to Support section using the button in the menu below NoSQL. I'm already logged in so it shouldn't be an issue, plus I can then select Home from the menu to get to the actual support page.
I can no longer reproduce it either, so it looks like it's fixed now.
Does this happen to you all the time? We've not been able to replicate this behaviour here.
The support and documentation runs on a different site, and there is some SSO between the 2 platforms. it appears to be working now, but if you are still seeing this let us know and we'll look further.
