I've just upgraded to 6.7 but for some reason I can't enter the control panel using the same username and password I've always used.

I've checked it a few times (in fact this password is actually retained by the browser, so I know I'm not typing it wrong), on a few different machines and it keeps telling me I've entered the wrong log-in information.

Help!
