A Database Error Occurred Error Number: 1054

Unknown column 'fingerprint' in 'field list'

SELECT member_id, admin_sess, fingerprint, sess_start, login_state, last_activity FROM (exp_sessions) WHERE session_id = '61d62d6d1f526c3ea67c9561cbef791a470a7101' AND fingerprint = ''

The "Fingerprint field" is missing in DB.

Go to Database to trigger this query.

ALTER TABLE  `exp_sessions` ADD  `fingerprint` VARCHAR( 40 ) CHARACTER SET utf8 COLLATE utf8_general_ci NOT NULL AFTER  `user_agent`
