Remove the Discount Codes info on Invoice

On the html invoice the discount code appears as a link to a popup window. Is there a way of removing this link?

The reason is that when I use the PDFOC, the invoice prints the link to the popup window, and the whole invoice gets pretty messy. I figured that the easiest way to omit this would be to remove the link, as it is pretty unnecessary.

There might be some other solution to fix this that I am not aware of?

If you don't like this, edit the file includes/modules/order_total/ot_coupon.php, go to the function process() and delete the code which is appended to $this->title. A more sophisticated fix (which I am adding to the next version of Quantity Discounts) would involve checking the current page and printing the link if the current page is checkout_payment.

I did as you described and deleted the code appended to $this->title in the function process () part. But I couldn't observe any changes on the html invoices. Will the changes only appear on new invoices created after the change?

Correct. To change existing invoices you would need to update your database.

Ok. Now I've tested with the changes. But it does not remove the link to the popup window, hence the same link to the popup is printed in the PDFOC invoice. Isn't there a way of disabling this popup window?
