I’ve been happy using the WP Discourse plugin for our podcast WordPress site to connect to our Discourse Community. I stopped seeing the Discourse discussions sometime ago after the latest plugin update.
I might be wrong but it looks like now the way to add it to a template is via Full site Editor (?). I might look to change but am very happy with my Anders Noren Garfunkle theme. It’s single post template has a layout that puts comments in a tabbed display at the bottom of the post, outside the range of widgets.
I did consider just manually adding a Discourse block to all posts, but for now have made an adjustment that inserts the Discourse discussions using the HTML code. In my child theme, I comment out the standard WordPress comments template (we only allow comments via Discord), and check the post meta data for a discourse ID.
