sampoyigi You're right, the corresponding tables should be deleted. This will definitely be handled properly in future version since models will be using Eloquent ORM.
Edw When delete Orders from admin panel, why not delete data from corresponding tables? eg from: ti_order_menus ti_order_options ti_order_totals Is this an error or are these data used in the future?
Edw Hmm.. This garbage was left from orders that were partially removed. They were assigned a status_id 0. But status with this status_id does not exist. Everything works fine, after cleaning garbage from tables manually.
