Ошибка 1054 - обновление Joomla 2.5 на 3.4 - Joomla 3.x: Общие вопросы

Она у меня возникла ошибка 1054 после (во время) обновления с Joomla 2 на Joomla 3. В админке - белый экран, на сайте это сообщение:
1054
Unknown column 'c.version' in 'field list' SQL=SELECT c.id, c.asset_id, c.access, c.alias, c.checked_out, c.checked_out_time, c.created_time, c.created_user_id, c.description, c.extension, c.hits, c.language, c.level, c.lft, c.metadata, c.metadesc, c.metakey, c.modified_time, c.note, c.params, c.parent_id, c.path, c.published, c.rgt, c.title, c.modified_user_id, c.version, CASE WHEN CHAR_LENGTH(c.alias)!= 0 THEN CONCAT_WS(':', c.id, c.alias) ELSE c.id END as slug FROM lux_categories as c LEFT JOIN lux_categories AS s ON (s.lft <= c.lft AND s.rgt >= c.rgt) OR (s.lft > c.lft AND s.rgt < c.rgt) LEFT JOIN (SELECT cat.id as id FROM lux_categories AS cat JOIN lux_categories AS parent ON cat.lft BETWEEN parent.lft AND parent.rgt WHERE parent.extension = 'com_content' AND parent.published != 1 GROUP BY cat.id) AS badcats ON badcats.id = c.id WHERE (c.extension='com_content' OR c.extension='system') AND c.access IN (1,1) AND c.published = 1 AND s.id=2 AND badcats.id is null GROUP BY c.id, c.asset_id, c.access, c.alias, c.checked_out, c.checked_out_time, c.created_time, c.created_user_id, c.description, c.extension, c.hits, c.language, c.level, c.lft, c.metadata, c.metadesc, c.metakey, c.modified_time, c.note, c.params, c.parent_id, c.path, c.published, c.rgt, c.title, c.modified_user_id, c.version ORDER BY c.lft

Обновлял через установку расширений, т.к. через компонент выдавало ошибку "Invalid login".
Что делать? Не пойму 

Я обновлял вот так: Обновление 2.5.24 до 3.3.0. Ошибка 1062 (бд)
