I tested the new addon for invoices 1.0.0 on a database which contained some data created by the previous version. I uninstalled the old one and after this I installed 1.0.0. With the old data everything was OK.
I wanted to start the numeration of invoices from 1 so I deleted the vm_bill, vm_deliveries and vm_delivery_item tables from database. Using phocainstall I created the tables again with no data in. Unfortunately after I did it the "obliterate" button disspareard.

The addon is working well I have icons to create invoice and delivery doc. Only the obliterate is missing...



Any idea what I did wrong?
