The admin page returns 403 Forbidden after being updated to the latest version

I've recently updated my Pi-hole version, but after I open the admin page, it returns 403 forbidden. The previous version did not return a 403 forbidden response. I've tried sudo dpkg -P lighttpd, sudo apt install --reinstall lighttpd, and sudo pihole-r, but it still returns 403 forbidden from the admin page.

The 8.8.8.8 DNS didn't resolve because the Indonesian government blocked it.

Expected Behaviour:

Going to the admin page or web interface should show stats, etc.

  • Raspberry Pi (i386 version) Debian GNU/Linux 10 (buster)
  • Dell Optiplex 990, Intel i3 core, 4GB of rams

Actual Behaviour:

Going to the admin page displays only a "403 - Forbidden Message" after being updated to the latest version. DNS blocking is still working before and after the update to the newest version.

Debug Token:

This is expected.

You need to add /admin to access the admin web interface.

I've recently updated my Pi-hole version

Please, as recommended read the release notes before update:

Sorry for my mistake. It works right now. Thank you so much for helping with it.
