Troubleshoot Product Bundling on Legacy Plans

Troubleshoot legacy Product Bundling issues in Infinite Options for stores that have not switched to Native Bundling, with common fixes.

About this guide

This guide applies only to stores using Product Bundling, the legacy bundling feature in Infinite Options.

If Native Bundling is turned on, see Add on product is not working as expected instead.

Product Bundling remains available for legacy plans, and many common issues can be resolved by confirming add-on products are active on the Online Store channel or reaching out to support. You can find common reasons for add-ons not to show on the backend of orders below:

Before you begin

Before troubleshooting, confirm that your store is using Product Bundling.

Signs you’re using Product Bundling include:

Add-on products are added to the cart as separate products.
The bundled product is linked to an Infinite Options option.
Your store has been using Product Bundling on a legacy Infinite Options plan.

If you’re unsure which bundling method you’re using, contact our support team.

Common issues

My bundled product isn’t being added to the cart

If the bundled product isn’t appearing in the cart:

Verify the bundled product still exists.
Confirm the product is Active.
Make sure it’s available on the Online Store sales channel.
Check that the option is still configured to add the correct product.

Check the product page

From the Infinite Options app, open the product using the Preview link.

If you see a red banner on the product page, your theme requires additional code for Product Bundling and Required Fields.

Contact our support team and let us know you see the red banner. We’ll install the required code for your theme before continuing with any additional troubleshooting.

“Cannot find variant” errors

This error means Shopify can’t add the bundled product to the cart.

Check the following:

Open the bundled product from the Option Set.
If the preview displays “Sorry, no products match this option set to preview,” the original bundled product has been deleted. Update the bundle to use the current product.
If the product opens successfully, verify that it is Active and available on the Online Store sales channel.
Test the product page again after making any changes.

For detailed instructions, see Resolving “Cannot Find Variant” Errors.

Here is the full guide: Solving Cannot Find Variant Errors

The bundled product was deleted

If the bundled product no longer exists and is displayed as a warning on the app dashboard

Create or restore the product.
Edit the Product Bundling configuration.
Select the correct replacement product and variant.
Test the bundle again.

The wrong product is being added

Review the Product Bundling settings and verify that the option points to the intended product and variant.

Another app may be interfering

Some apps can interfere with Product Bundling by modifying the cart, preventing more than 1 product from being added to the cart.

Examples include:

Cart drawer apps
Bundle apps
Subscription apps
Upsell apps
Cart customization apps

Temporarily disable the other app or test in a clean theme or product to isolate the issue.

My option selections aren’t appearing

After adding the product to the cart:

Confirm the bundled product appears.
Confirm the correct variant was added.
Confirm the selected options appear as line item properties.
Place a test order to verify the information carries through checkout.
