I migrated an old Joomla 1.5 server to a shiny new Joomla 3.3 server using the tool SP UPGRADE at http://cyend.com/extensions/extensions. Now I can't seem to login and I fear its because all the user passwords in the DB look like 'MD5':'Salt' which is the old way to create passwords. I understand the newer code uses a based password. All of the methods I see described about pasting in the old style 'secret' password are not working. How do I reset a password in Joomla 3.3?
