Ошибка MySQL Неизвестный столбец в списке полей при переносе базы данных на новый сервер (Windows)

Я изменяю свою базу данных с одного сервера на другой, и в режиме отладки у меня есть эта ошибка в базе данных MySQL.

WordPress database error: [Unknown column 'tb.adult_price' in 'field list']

Я думаю, так все и начинается

Я ищу в моих файлах php, и я нашел код:

    $query .=",CASE

THEN
CAST(tb.adult_price AS DECIMAL) - ( CAST(tb.adult_price AS DECIMAL) / 100 ) * CAST(tb.discount AS DECIMAL)

ELSE tb.adult_price
END

ELSE tb.infant_price
END

ELSE 0
END AS st_tour_price";

Я не знаю много о SQL и базах данных ..

Есть ли способ это исправить?
