The full installation of PrestaShop includes several demo products and other data. When deleting the demo products, you may see the following error. This tutorial will walk you through how to resolve this "error occurred during deletion" issue:

At first glance, this is a vague error that really doesn't specify what issue caused the error. Fortunately, with a little research, we were able to find a solution.

The demo data included in the full PrestaShop installation also contains a sample order. We will need to cancel that order before we can delete any products that are tied to that order.

1. In your PrestaShop back office, click on the Orders tab.

   

2. Click the view icon for the "J. Doe order."

   

3. Choose Canceled from the order status drop down menu and click the Change button.

   

Now we can return to the Catalog tab in our PrestaShop back office and delete the remaining demo products.
