So I have had my Lemmy up and running for a few weeks now and I thought I would like to enable federation.
I saw the note to insert this code https://github.com/lemmynet/lemmy/blob/main/config/config.hjson#L64
And I saw somewhere we could do it through the interface.
So I click on the settings cog and insert it into the Admin Settings - Site Configuration box and click save.
But I always get an error message that says "Couldn't update this site"
What am I doing wrong? How do I enable federation?
Thanks is advance for your help.
