Ever since I moved the forum from the test site to the permanent domain I've encountered innumerable problems. The most serious one at the moment is that new users are unable to register. I've tested this and what happens is the user gets a confirmation email, but when they click the link it tells them "Your account is currently awaiting confirmation." Six hours later, no confirmation. I've had to confirm manually. I have "Enable Registration" and "Enable Email Confirmation" set in options > user registration. There are other problems, but I'll take one at a time.
