Anytime you try to go to the Hikashop Dashboard in the Admin area, it creates this error:

1054 Unknown column 'a.user_created' in 'where clause' SQL=SELECT *, SUM(order_product_quantity) as Total FROM #__hikashop_order as a LEFT JOIN #__hikashop_order_product as prod ON a.order_id=prod.order_id LEFT JOIN #__hikashop_product AS p ON p.product_id=prod.product_id LEFT JOIN #__hikashop_product_category as cat ON cat.product_id=p.product_id OR cat.product_id=p.product_parent_id LEFT JOIN #__hikashop_category as c ON cat.category_id=c.category_id WHERE a.user_created > 1451606400 AND a.user_created < 1469695997 GROUP BY c.category_id ORDER BY Total DESC LIMIT 10

It was this report: Five best categories over the last two weeks
Clicking on this report, even when it is unpublished, causes that same error.

Since I don't know what selections made that report I can't exactly recreate it.
