Pandaria "The information you have added is not valid"

Hi

Since yesterday, whenever I would try to log in, I get a message saying my account name or password is invalid. I know I haven't changed anything on my account. How do I fix this?

it is the same account you used to open this thread? Because if you can log-in on website then you should be able to log-in in-game as well; unless your password has more than 15 characters, in that case it is too long to be insert on client so you need to use a shorter one.
