I have a local instance running. When I'm logged in as user1, log out,
then try to log in as user2, I keep getting the "You have been logged
out" message.
Its as if the browser's cache is retaining some information. To get
around this, after I log out as user1, I have to click on Analyze Data,
then click on Log in to log in as user2.
I'm running Safari on Mac, but have noticed this with Firefox as well.
