For the last week or so on IOS 7's Safari, when I'm browsing the LA board, every time I return to the main LA board from a post, I am logged out. Then I need to click the login button to make things right. Until the next time I go to the LA board. Reloading doesn't solve this using the back button doesn't solve this. But I don't seem to be logged out on other boards. It is annoying but not fatal.
