It looks like you've got some ghosts from an early bug still haunting your browser. To fix it, find a Logout button (there's one on the front page) and click on it to explicitly log out. Then restart your browser and login again. Please let me know if you still have problems after trying this. Sorry for the inconvenience.
Does it show you as logged in on the front page? Does it show you as logged in in the forum? Does it show you as logged in in the Community? What browser are you using?
It shows me logged in everywhere until I click to go to "my wakespace" or to check my messages or get into my personal profile and then it kicks me into the log-in again.
I'm using firefox.
Are you logged in on any other computers or smart phones?
I was having problems and had to log-off, close the browser, and clear my cache....not only on my laptop, but also on my iphone. It seemed to do the trick.
