If I go to my 'test' site here: Login Page and deliberately enter false log-on credentials, I get an 'Invalid password' error, which is fine.
Yet, if I then close my browser and then go back to the same site, I can still see the same error message. This happens in IE10 and not in Safari (on Windows).
What might be the reason for this, please? Is it likely to be a coding problem or a browser one?
