Good call, I tried it out on our staging site but unfortunately it didn’t fix things…
On Chrome I see errors like the following:
Failed to execute 'postMessage' on 'DOMWindow': The target origin provided ('https://test-discourse.comses.net') does not match the recipient window's origin ('https://test.comses.net').
(from The Garbage Can Model of Organizational Choice)
Other people here seemed to be able to fix this by ensuring that the DiscourseEmbed.discourseEmbedUrl was the same as the referring URL but I verified that it was still correct… I poked around the Discourse logs (should I be looking at /var/discourse/shared/standalone/log/rails/production.log ?) but didn’t see any errors there either… any other ideas on places to look to troubleshoot this?
An example from the Discourse logs:
