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.
[deleted] 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?
[deleted] 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.
