WC somehow adding unwanted product to customers order

  • Hello,

    We’ve had about 10 customers with this problem: they add a product to their cart, check out and pay, and then the order suddenly shows an additional product (front and back end.) The customer was not charged for the added-on product.

    It appears the “bonus” product was ordered by someone earlier in the day, which leads me to believe it’s a caching issue?

    We’re running WC 3.0.7, PHP 7.0.19, SG Optimizer
    This started happening after upgrading to WC3.

    Appreciate any help as I am clueless with this!

  • What plugins besides woocommerce are you running? Have you excluded the Woocommerce from the caching plugin?

    Yep, Woocommerce is excluded from caching.

    Running:
    EWWW Image Optimizer / WooCommerce – Gift Cards / Google Analytics Dashboard for WP /
    MainWP Child / Postman SMTP / SG Optimizer / UpdraftPlus / WooCommerce Chained Products / WooCommerce Stripe Gateway / WooCommerce MailChimp / WooCommerce Sequential Order Numbers Pro / WooCommerce Variation Details on Page Product / Wordfence Security / Yoast SEO

    I don’t know how to replicate my problem (it doesn’t happen with every order) so I can’t really disable the plugins to see if they’re causing the issue.

    And the problem had never happened before but started suddenly.

    Well there are a couple of things go with to pursue and troubleshoot the problems

    To try and narrow down what’s happening, look at the orders where the previous customer ordered the product and the order where its being added, the products being added, the other products in the orders, and even the customer accounts. Look for common denominators. Is it only happening when say, its from a certain category, or a certain type of product, was a coupon used or a certain payment gateway even shipping method. Are the products chained?

    – create a duplicate site (files and database) either locally or in a separate folder on your website turn on error and query logging create dummy accounts and starting with the products that are in the orders involved, place orders until it recurs. Change the theme, does it still happen? and back trace how it gets put in the order

    3 was a big change, the way the order and other data is accessed especially, and and as they tighten it up, I think many plugins will either need to be updated or replaced.
