Suddenly, I find I can't get into Apple Discussions. If I click on Log In, it refers me to a new page and asks me to set up an Apple ID, even though my present Apple ID is already displayed. If I fill in the blanks, it tells me I'm not authorised to create an account. If I go to any topic in Apple Discussions, it tells me there are no posts on that topic, while showing five pages. WTF??
