Cannot process new invoice.
You need to be much more specific. Have you read the Guide: https://www.manager.io/guides/7178?
The EDIT CLONE COPY etc does not appear on the top of the invoice when creating a new invoice.I have been using Manager for some time but after reloading Windows 7 this problem started
The buttons you mention have never appeared on the entry screen when creating new invoices. They appear on the View screen, after an invoice has already been created.
When you click on Create when doing a new invoice it does not create a new invoice so I don’t get to the view screen.
Then you are doing something else wrong. What edition are you using (desktop, server, or cloud)?
I am using Desktop version 19-10-75
The current version is 19.6.63 or so
There is no 19.10.75!
