I have a drupal 7 site running Civi 4.6.5 and using it for event registrations.
When attempting to view Participants from the Event page, I receive a DB Error: syntax error. See backtrace below. I am able to view a report of registered participants without an issue - just problems using the icon on the event page. Any ideas?
