The website is www.resultswithlucy.com. Yes, it is a home computer and I am the only user. This is the only site it happens on. I can access emails, Facebook etc with no problems.
If I put in an incorrect password it gives me the error message. If I enter the correct details it doesn't give me the message but takes me back to the login page as if I have never entered anything.
I haven't tried another browser yet.
