language.
- Install the 'eCommerce' module.
- Go to the website.
- Go to the shop menu, and click any product from the product list.
- Click on the Edit button and try to edit any float or
monetary section like a product price (eg. change a product price from 750 to
70) and click on the Save button.

And traceback will be generated.
