I changed the condition with isset($author) to !empty($author), which should now allow you to write to a pre-existing settings file whose author has been set to the empty string. Since the login() function can still return a true value when an empty string is passed to it as the userid, I added some lines of code to set $userid to the value of this function if it was previously empty. That should prevent anyone from saving a settings file with an empty $author string.
