Battle.net API error on viewtopic.php

[Mythos]

Following error occurs when I've activated the Battle.net API. Seems that the SQL-Query is trying to access a non existing column.

SQL ERROR [ mysqli ]

Unknown column 'last_modified' in 'field list' [1054]

SQL

INSERT INTO phpbb_pbwow3_chars (user_id, updated, tries, game, last_modified, name, realm, battlegroup, class, race, gender, level, achievement_points, url, avatar, avatar_url, calc_class, total_hk, guild) VALUES (2, 1425985639, 0, 'wow', 1425921589000, 'Dibella', 'Aman\'Thul', 'Reckoning / Abrechnung', 9, 2, 3, 97, 2155, 'http://eu.battle.net/wow/character/amanthul/Dibella/', 'internal-record-3680/179/100495795-avatar.jpg', 'http://eu.battle.net/static-render/eu/internal-record-3680/179/100495795-avatar.jpg', 'e', 10, 'Gods of War')
