Error setting takepos

how to fix this error

My coffee machine is not working : How to fix it

that’s not very helpful

Did you “Enable features for Bar or Restaurant”

it’s located here:
Home, Setup, Modules/Applications, takepos, cogwheel for settings, Bar Restaurant

Do you have any product categories?

“Products | Services”, Tags/categories

Also which version of Dolibarr ?

Of course not !
But I was a bit piss off by the way he is asking the question.
