No host, no service after running Node Wizard

oh gosh, i just work around for this problem since 2 days ago. i revisited this article many times but i was understood the article that u give me. Before i was delete the icinga2.conf for uncomment and recomment the include_recursive conf.d & include conf.d/api-users.conf too.

Here what i did that make the hosts and services back.

  • Delete the icinga2.conf on etc/icinga2/icinga2.conf

  • Copy icinga2.conf.orig then paste it, then it become to icinga2.conf(copy).orig

  • Rename icinga2.conf(copy).orig to icinga2.conf

  • Then run icinga2 node wizard, and don’t forget to type n for
    Do you want to disable the inclusion of the conf.d directory [Y/n]:

Many thanks @yhabteab for helping me realize the step.
