I don't know if this will help solve the problem, but clicking from one section to another just now I got an error 520 message that told me my browser is working, Cloudflare London (whatever that is) is working, but the host (AnswerBank) is not.
I can't see any threads but I couldn't get on AB at all between 1pm and 3pm today and then I went out and now it's OK - was that the same for everyone?
