I have to create a Odoo system for a project course, I made a e-commerce website where users can buy some books (it's a fictive business).

So I included and configurated some module: website, e-commerce, sales, CRM, inventory, purchase, accounting, employee, job offer, ...

It seems that all is working, except for one thing: when someone buy an article, the order is not displayed in the website order module. Neither in unpaid order and order. (The sale module displays the order but not the e-commerce module)

Can someone help me ?

version: Odoo 12.0+e (Enterprise Edition)
