Error No: 1242 on OpenCart how to solve?

Question

MySQL

Transferred the site to a new host, connected everything, did everything and the error on all database pages is identical to that database.

Mistake:

Fatal error: Uncaught exception 'Exception' with message 'Error: Subquery returns more than 1 row<br />Error No: 1242<br />SELECT DISTINCT *, pd.name AS name, p.image, (SELECT md.name FROM oc_manufacturer_description md WHERE md.manufacturer_id = p.manufacturer_id AND md.language_id = '1') AS manufacturer, (SELECT price FROM oc_product_discount pd2 WHERE pd2.product_id = p.product_id AND pd2.customer_group_id = '1' AND pd2.quantity = '1' AND ((pd2.date_start = '0000-00-00' OR pd2.date_start < NOW()) AND (pd2.date_end = '0000-00-00' OR pd2.date_end > NOW())) ORDER BY pd2.priority ASC, pd2.price ASC LIMIT 1) AS discount, (SELECT price FROM oc_product_special ps WHERE ps.product_id = p.product_id AND ps.customer_group_id = '1' AND ((ps.date_start = '0000-00-00' OR ps.date_start < NOW()) AND (ps.date_end = '0000-00-00' OR ps.date_end > NOW())) ORDER BY ps.priority ASC, ps.price ASC LIMIT 1) AS special, (SELECT points FROM oc_product_reward pr WHERE pr.product_id = p.product_id AND customer_group_id = '1') AS reward, (SELECT s in /home/vanna815/domains/4vanna.com.ua/public_html/system/library/db/mysqli.php on line 40

Something to do with the base. Try each of the subrequests manually (in phpMyAdmin for example). What will happen?
