whenever i use /back command it says (could not execute command 'back' command. No previous location found.i am using the 1.20.6 version maybe that the problem

What are you trying to go back to?

By default, /back only tracks previously teleported-to locations. If you want to go back to a death location, you need to enable allow_back_on_death in the config.

thx so much
