We just upgraded to v5 from v4. emailed reminders are sending but have a URL that gives a 404.
the button on the email produces: https:/ourinvoice.domain.com/invoices/1402
It looks like the upgrade doesn’t fix $viewButton → $view_button. $viewButton doesn’t work and gives a 404 when clicking the generated button. $view_button produces a link that is usable.
All clients had a payment terms set. However we have several who’s recurring invoices went to 7 days. Which we’ve never used. It seems to be random. Many kept their setting post upgrade but quite a few reverted to 7 days which I believe is the default.
