Order cancelation for not registerd users

Hi,

Sure. You need to do two things:
1. Configure the "Cancellable orders statuses" setting of the HikaShop configuration page. So that you allow the customers to cancel orders only for some statuses.
2. You can edit your emails via the menu System>Emails. There, in the HTML version, you can add such code:

<a href="<?php echo hikashop_completeLink('order&task=cancel_order&email=1&order_id='.$data->order_id); ?>">Cancel the order</a>

Hi,

Do you see the cancel button on your orders listing in the frontend ?
If you don't, it's normal that the link doesn't work. As it means that you don't have the right to use it.
And in that case, it means that the "Cancellable orders statuses" setting is not correctly configured for what you want to do.

Hi,

Create an order with the new button in the backend order listing and assign it to yourself.
Then, log on the frontend and access a menu item of the type hikashop order listing (that you would have created before via the Joomla menu manager) and there you'll see your order along with the cancel button.
Try to click on it and see if that works. Then, try the link in the notification email that you can send to the customer when you change the status of the order.

Based on what works and what doesn't, that should already narrow down the issue.
