Previously I had created a role and added a user. The user
waited several weeks to try to login and now is receiving a message
that his role is no longer valid. When I login to administer the
site his role is not listed and when I re-created the role I can't
add him because his name is 'grayed' out and indicates that he is
currently assigned to the previous role.
Has anyone else had this problem? How can I fix it?
