Embeded comments show in the blog post. Which links to the discourse site. Which does OAuth(?) authentication to my app. The Login page of my app is too small to show in the iframe created by the embedded code.
Oh, snap! I think I see what you mean. Discourse is configured not to show these topics without a logged in user.
I have this option enabled: login required - Require authentication to read content on this site, disallow anonymous access.
So maybe that’s the problem. I don’t remember why I turned that on (I configured discourse several months ago). I think I can turn it off, and then configure any private categories individually if I want them hidden.
