There are 2 types of Discounts (Shopping Cart Rules) Working on the Website right now:

  1. Coupon Codes - Working Absolutely Fine BUT - Subtotal does not get Updated. Ex: 10% Off on Rs. 500 and Above - When I apply the Coupon Code, it shows perfectly before Subtotal but the Grand Total still remains the same(without discount)

  2. Without Coupon Code Discount - Working Only On Checkout Page after I select a Payment Method. - Eg: ABC Product has a Coupon Attached to it giving Free Shipping on it BUT this is not Reflecting in My Basket Subtotal and is Only Visible in Checkout Page's Subtotal upon selecting a Payment Method - NOTE: The Subtotal where Shipping Charges are currently visible used to Show a Value of ZERO when ABC Product was added.

    1. IMP NOTE. This Issue of Grandtotal related to Config because this was Non-Existent and suddenly popped up after Migration to a nginx Server. - The Server Admin has thoroughly verified and is sure of no errors on Server Side.

    2. I have cross checked all Settings and Discount Rules in Backend - No Defaults found

  3. No Tax Calculation is used on the Website

Thank You for Reading the above and I hope you, the reader would be able to contribute towards resolving this.

    Thanks, Its works for me can you add a description why it happened. – Saurabh Taletiya Dec 24 '17 at 12:45
  • @SaurabhJain the _getSortedCollectorCodes() method has been updated based on the php 7.0 (While applying coupon code, Totals are not updating due to uasort not working in php7 then modified the _getSortedCollectorCodes()) – Nagaraju Kasa Dec 26 '17 at 6:51

Had this same exact problem (#1) on CE 1.9 running PHP 7, applying the Inchoo "PHP 7 compatibility extension for Magento 1" solved the issue!

Seems like it is an issue with PHP 7 / uasort function. In another ticket it you told that you have switched server to nginx and most probably you have also updated php.

You can see more detailed answer why it's happening here - https://stackoverflow.com/questions/34281113/the-different-behavior-of-the-function-uasort-in-php-5-5-and-php-7-0

I have the same issue with Magento 1.9.3.2 and I just downgraded my PHP from version 7.0 to 5.6 and it fixed the problem instantly. :D

If you upgrade your server to php 7 then this issue arise.

This module fixed things up for me: https://github.com/hartmut-co-uk/magento-php7-totals-fix
