I just installed on 3.6.8. gives me this error:

Database error in vBulletin 3.6.8:

Invalid SQL:
SELECT user.userid AS user_id, user.email AS user_email, invitation.email AS inv_email, invitation.acceptedby as inv_id
 										FROM vb_user
 										LEFT JOIN vb_invitation
 										ON user.userid = invitation.acceptedby OR user.userid = invitation.email
										WHERE user.email = 'someone@gmail.com'
										OR invitation.email = 'someone@gmail.com';

MySQL Error  : Unknown column 'user.userid' in 'field list'
Error Number : 1054

That makes sense, 'user.userid' is an unknown column becuase the query isn't 'from vb_user as user left join vb_invitation as invitation'
