Problems With Steps in Checkout Workflow

I activated the debug of joomla and tried about an order on your front end. I got the error:
1054 - Unknown column 'discount_minimum_products' in 'order clause' SQL=SELECT * FROM andhikashop_discount WHERE discount_type='coupon' AND discount_published=1 AND discount_auto_load=1 ORDER BY discount_minimum_order DESC, discount_minimum_products DESC

Which means that the database structure couldn't be updated when you updated HikaShop (you probably didn't allow your mysql user to use the ALTER capabilities in its privileges. You should do that for next updates.

That also means that you might be missing other columns in the hikashop tables in your database.
You can open the file adminsitrator/components/com_hikashop/install.com_hikashop.php and search for the query responsible for the missing column and then run that query (you need to change the prefix of the tables) via phpmyadmin so that the column gets added to the table.

Could you do screenshot of your checkout page and give us the checkout workflow you're using so that we can help you ?

For the checkout workflow edition ?
There is no confirm or end icon as they are handled automatically.

If you're talking about the checkout progress bar on the front end, it depends on the options you set in the Checkout tab of the configuration. For the end step, you could just turn it with the option "Display checkout progress bar". For the confirm step, it depends on your checkout workflow.
