Unable to import duplicate product – Please remove the duplicate product in your database

The export log shows a message like:

Cause

The module has detected that the product reference is used more than once in your database, which is not allowed.

What to Do

Each product and each combination must have a unique reference.

Refer to this guide: Validate your catalog structure

Steps to Fix

1. Copy the reference shown in the error message.
2. Paste it into the PrestaShop back office search bar.

If multiple results appear, it confirms that the reference is duplicated:

⚠️ Important: If the duplicate is from a product combination, it might not appear immediately. Click on the product in the results and check the "Combinations" tab to verify the reference.

3. Edit the references to ensure all are unique.
