Здравствуйте, хотел Обновится с 3.8.6 до 4.0.7 помогите разобраться как исправить данную ошибку (ранее были проблемы с ?????? ) :

Database error in vBulletin 3.8.6:

Invalid SQL:

(SELECT 'package' AS classtype, package.packageid AS typeid, package.packageid AS packageid,
package.productid AS productid, if(package.productid = 'vbulletin', 1, product.active) AS enabled,
package.class AS class, -1 as isaggregator
FROM package AS package
LEFT JOIN product AS product
ON product.productid = package.productid
WHERE product.active = 1
OR package.productid = 'vbulletin'
)

UNION

(SELECT 'contenttype' AS classtype, contenttypeid AS typeid, contenttype.packageid AS packageid,
1, 1, contenttype.class AS class , contenttype.isaggregator
FROM contenttype AS contenttype
INNER JOIN package AS package ON package.packageid = contenttype.packageid
LEFT JOIN product AS product ON product.productid = package.productid
WHERE product.active = 1
OR package.productid = 'vbulletin' );
