It's painfully silly, stupid.
It's an oversight 🤷‍♂️

Take a look here: https://github.com/InvoicePlane/InvoicePlane/pull/1473/files

If you add those 2 lines in that file you won't have that problem anymore.

Those 2 lines will be added in 1.7.2
and until that time can you add those 2 lines in that file?

Sorry about that :) but i manage to fix the error by changing the invoice theme on the settings.
i upgrade it from 1.6.3 to 1.7.2 which cause me those problem my mistake :)

Sorry about that

Don't worry about it, it's an oversight by the maintainers, not by you 😉

It's silly, because it's such an easy solution.

Great that you easily could solve the problem, that's the most important thing.
