Problem with Coupon and Checkout

Hi,

Regarding the warnings in your log, there's nothing to worry about and they are not linked to your issue. It's just some missing check when doing some calculations when the checkout system loads the cart.
You can ignore them and we'll fix them in the future so that they don't appear in the log.

The patch mentioned in the other thread has been added to HikaShop 2 years ago and it is still there.
So while your problem might look similar, it's another problem.

As you read on that other thread, to be able to understand what's going on, we need first to be able to reproduce the issue (so we need instructions to do that... what coupon code to use, what product to add to the cart, etc). Then, we need to see how your checkout and coupon are configured. And if there is really a bug, we might need a backend or FTP access to be able to debug the situation.
Since you say that the issue is urgent for you, please provide as much of these as you can so that we can look into the problem as fast as possible.
If you wish to provide these in private, you can use our contact form:

Please make sure you include a link to this thread for reference.

Hello,

We have received your references and where able to see your issue on your website, but we weren't able to reproduce it on our website.
Plus, unfortunately we haven't the full access of your backend, in details we can't reach the main configuration of HikaShop, please adjust the provided backend access in order to have the full access.

Other point, it's really a shame that you have remove the default template (ProtoStar), suddenly you deprive yourself of being able to test with a default template, I mean, because maybe your issue come from your template ?... Restore a default template please.

Other theory, you have some override view in Display => Views, and checkout view group.
=> Try to save on your side all your override views, remove its from your website, and process some tests again.
If that didn't change anything you can restore your overrides view.

We are awaiting your returns to be able to progress on your subject.
Regards
