Hello, 

In case of uninstall the module, you've lost the all information. 

In the place of uninstall you can update the sales module again and check it. 

Also, this cases case happen in that case the menu permission was changed or anything else. 

thanks.

I have the same issue. I can't launch the update as solution, since I'm using the free version. Wouldn't be any problem in my DataBase connection if I uninstall and reinstall the "sales" module? Or it would destroy all my previous configuration?

it seems you may removed some access. Please check the sales access under settings >> Users.

Also you can try to upgrade sales module to reconfigure the entire configurations.

Everything seems to be ok in this area. I can't attach any picture due to my account state as new member in the forum, but it shows my user as "Responsible" on the "Sales" application permissions.
 

Go to Settings

Users & Companies-> Users

Open the account and check the sales access rights enabled or not.

Please choose appropriate access ights and check.
