Rebuilding user profile

I am using YAML-based configuration for HASS. I accidentally deleted some files and now all my user information is lost, but the configuration is not lost. So I recreated my owner user. HASS itself works, but some things are missing:

  1. When I open Configuration / Server Controls, only the “restart server” option is visible. Previously, there was also a “check configuration” and some buttons to reload parts of the configuration.
  2. I cannot find the option to create another user.

How can I get these back?

Sounds like “Advanced Mode” in the user profile is disabled.

Thank you, it solved the problem.
