When I try to edit my account I get:

sorry is not a valid username

however, it never asked me to enter a username and I was logged in

Are you signing in with a capital W and a capital P just as your username is written? If not that is most likely the problem and I can fix that, I just need to know at what part you have a problem.

Does it pop up when you first load the page or when you are trying to save it?

Thanks dj I got it to work. I went to my account at the top of the page and so was able to make some changes.
