• Phoenix version (mix deps): 1.7.14

• Operating system: OSX
• Browsers on which you attempted to reproduce this bug (the more the merrier): Chrome latest

Actual behavior

I am trying to install beacon into an existing app via igniter, as advised in the docs.
After running the mix igniter command, I found several issues.
Non-blocker, the config

  insights: [site: :insights, repo: Nui.Repo, endpoint: NuiWeb.Endpoint, router: NuiWeb.Router]

Is added only to the runtime.exs. Fixed by copying it to dev.exs.
Now I can access the default setup for Beacon, which is great.
When I try to access the admin section though, I get an empty page, and this message in the console.

What am I doing wrong?

Expected behavior

Expect to be able to get to the admin page

Hi @dantodor, thanks for trying Beacon! The debug message you shared is unrelated to your issue. That message says the css file didn't load, but your issue is that beacon_live_admin isn't connected to any beacon site(s). Did you use the command

mix beacon.gen.site --site my_site --path /

to generate the site(s)? Or have you set up the Beacon site(s) manually? Any additional details you can provide would be helpful troubleshooting the issue, maybe even paste the Beacon.Config you are using.
