Hey there!
I’m not sure if using a generic whitelist and then moving topics around would work - but certainly worth testing if that would be a suitable approach. Would be interested to hear the results if you do try it out.
Couple of notes:
-
It looks like your “Post to Category” of
Staging
has a padlock on it, which means it’s locked and not public. This is what I meant in my last comment - I ran into the same issue when embedding Discourse comments on my site, and found that I had to test it on a public Discourse category. -
Your Discourse embed code is commented out with
{{!--
,--}}
– remove these tags and re-upload your active theme in Ghost Admin and then it should work.
Hope that helps!
