好主意，我在我们的测试站点上试过了，但遗憾的是问题仍未解决。
在 Chrome 中，我看到如下错误：
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').

这里的其他人似乎通过确保 DiscourseEmbed.discourseEmbedUrl 与引用 URL 一致解决了此问题，但我已确认该值仍然正确。我查看了 Discourse 日志（我应该查看 /var/discourse/shared/standalone/log/rails/production.log 吗？），但那里也没有发现任何错误。还有其他建议的排查方向吗？
以下是 Discourse 日志中的一个示例：
