Advanced Developers only:

To completely remove Canada Post module you will need to dump all of the product fields made by the shipping module install - after uninstalling it. This SQL Update will also permanently remove the data within so... ONLY use this for upgrades and testing - Best not to lose manually entered data.


Backup the database now. Twice. And test your backups.


ALTER TABLE `products` DROP `products_weight_type`;
ALTER TABLE `products` DROP `products_dim_type`;
ALTER TABLE `products` DROP `products_length`;
ALTER TABLE `products` DROP `products_width`;
ALTER TABLE `products` DROP `products_height`;
ALTER TABLE `products` DROP `products_ready_to_ship`;


Future Twitch versions Base6 will have these fields included in the core to ensure there is no change or need for changes when installing/uninstalling shipping modules.
