I have been using K2 and the K2 User module for login and registration without problems. Last night I used the upgrade function in the Joomla administrator area to do the upgrade from 2.5.8 to 2.5.9. All seems to work fine with log in and use, except now when a new member tries to register, they get the registration form and when they submit the form to register, they are taken to a component not found page /component/user/
