Migrating Discourse comments from WordPress to Ghost

I’m in the middle of trying to migrate my blog from WordPress (with Discourse comments) over to Ghost (with Discourse comments), and while having set up comments using the instructions at Official Ghost + Discourse Integration, I’ve run into a few issues to resolve.

Most importantly, when I go to a post that had existing Discourse comments (via the WordPress plugin), the comments section on the page sticks at “Loading Discussion…” forever. I had expected, and of course it’s rather crucial, that such embeds would link to the existing topic matching that URL.

Has anyone else migrating from WordPress to Ghost figured out a way to make that happen?

(See, for example, Spooooky and its corresponding topic Spooooky - General - The Eldraeverse .)

The configuration seems correct; the Discourse forum might have more information on this topic.

Thanks. I’m having some success getting it sorted out over there now.
