I am creating this new topic only as a visible reminder because references to the missing invoice stamps got buried in other chatter on unrelated topics. This is a known problem, not a new one.
The latest version (16.11.38) puts the stamp back but only to the original plain theme.
so the new themes that create by us will not get the stamp?
can you please make it possible for us to get the stamp (with our new themes)
Have a look how the stamp has been implemented in default theme. You can then copy & paste the code to your custom theme if you like.
