Buy Now button routing to wrong product on checkout

Technical Q&A

I am having having a problem on my website Prestige theme 11.1.0 vesrion. When i am going on any product page and clicking on “Buy Now” button directly instead of adding the product to the cart, an altogether different product is getting added on checkout. I have created a video link also: https://drive.google.com/file/d/1jT6cuk3t8vwVV6SuXfuVwSkRe6mRSD8I/view?usp=sharing

My website url: www.kavipoetryart.in

Could anyone please let me know solution to this problem? Thank you in advance.

Hey @kavipoetryart

Upon clicking the “Buy Now” button, the console gives this error below as shown in the screenshot so it’s most likely a theme bug which is causing that. Have you made any code changes within the theme files?

No, i haven’t made any changes to the code. how can i resolve this issue?

This usually happens when the “Buy Now” button is not correctly linked to the product variant or cart form. Have you checked if the product form ID or variant ID is being passed correctly in the Prestige theme settings?

Hi @kavipoetryart

we need to check the “Buy Now” button code. Have you made any custom changes to it?

Hi @kavipoetryart,

If the Buy Now button is routing to a different product, I would treat this as a high-priority checkout flow issue and avoid testing on the live theme only.

I would check:

1. Whether the issue happens on every product or only specific products

2. Whether the product form contains the correct variant ID

3. Whether any custom JavaScript is modifying the form submission

4. Whether a recently installed app is changing dynamic checkout behavior

5. Whether the same issue happens on a fresh theme copy

Since you are using an older Prestige version, I would also test this on a duplicated theme before making changes.

After fixing it, I recommend running a small launch/checkout QA checklist: product page, add to cart, Buy Now, discount code, automatic discount, shipping rate, and checkout.

If you can share whether this happens on all products or only certain products, that would help narrow it down in this thread.

Checkpoint: Store Scanner will not replace debugging this specific button issue, but it can help catch related store health problems after the fix, such as leftover app code, slow scripts, product content gaps, and discount issues.

Hi @kavipoetryart

We have checked your store URL. I think you have disabled the buy now button for the time being.

You can enable the buy now button to test the following scenarios:

  • Disable all non-essential apps temporarily from customization and test the Buy Now button — if it works, re-enable apps one by one to find the culprit
  • Test on a fresh browser session or Incognito tab
  • Check if it happens on all products or specific ones — if it’s only certain products, the issue may be tied to products with multiple variants vs. single-variant products
  • You can download the latest theme version and check the issue on that

Since this is a theme issue, you can contact Prestige’s theme support directly

Thank You
