zc 1.5.7, just upgraded in July
php 7.3 (have now upgraded from 5.6 after this happened)
template - no issues with it / no mods that change core files
One order added sales tax but three orders later, sales tax is not included. No changes to the site during the week between the two.
I recently changed the order total to make sure it sets as late as possible before the order_total as it was iffy before:
up Discount ot_group_pricing 290
Gift Certificates ot_gv 840
Low Order Fee ot_loworderfee 400
Quantity Discount ot_quantity_discount
Shipping ot_shipping 200
Sub-Total ot_subtotal 100
Tax ot_tax 300
Total ot_total 999
There are no group or customer discounts at work in the site.
Comparing the two orders, the products are both turned on for taxable. Both orders are one product only.
Both the shipping and delivery addresses are california.
The client was complaining about this problem before the upgrade if I remember correctly. I had checked it and saw nothing wrong then so it wasn't until after the upgrade that I dug into this. I did see this issue when someone used a discount coupon and that's when I changed the sort order in order total. But neither recent order has a discount coupon.
I had another well-versed zencart person follow behind me to be sure I had checked all the appropriate things and don't think I left anything out here in this post.
Any ideas?
