Is this an admin password? If so, do a search on this site for an forum thread on how to reset the admin password. You could feasibly follow the same instructions for resetting a users password, but really why wouldn't the 'forgot password' function work for your needs?
It is the admin password. I did follow the instructions. The problem is that it doesn't retain the changed password. I can't get the "forgot password" function to work, either. It just comes up with an error message. I'm just going to scrap the install and start over.
