ok. how do I send the account / password in private?
Anyway.. the problem is not showing anymore, as I put back bootstrap4bundle files.
before, in mobile phones view the visitor could see the three lines replacing the menu, but could not click in any way on that icon, so the menu was not showing.
I'm not using off canvas menu. And I didn't load the sample setup with all data, modules, settings... preset , so maybe I didn't replicate a correct default setup for ja_ego template.
