I added the define('WS_SERVER', true) in dispatcher.php but no luck. I can get the plugin to work with existing assignments: rosters can sync between Moodle and TurnItIn, students can submit assignments, teachers can grade assignments. However, when I try to create or modify an assignment it throws the webservices call error. So why would webservices work for some calls and say, not found in other calls? And why would the plugin work in 2.5 and 2.6 and not in 2.7?
