ERPNext + frappe need to change layout(footer & header) front-end. I tried to change base.html(frappe/templates/base.html) but nothing happened. Probably this is due to the fact that the html files need to somehow compile. Maybe someone have info how to do it?
UPDATE:
No such command "clear-cache".
Commands:
  backup
  backup-all-sites
  config
  get-app
  init
  migrate-3to4
  new-app
  new-site
  patch
  prime-wheel-cache
  release
  restart
  set-default-site
  set-mariadb-host
  set-nginx-port
  setup
  shell
  start
  update
It seems you're not in your bench folder.
When you create a new bench with, for example : bench init mybench it creates a new folder : mybench.
All bench commands must be run from this folder.
Could you try to run bench --help in this folder ? You should see the clear-cache command.
