我正在尝试显示 Discourse Block 以便展示我们已发布到 Discourse 的帖子。它们已成功发布。我在站点编辑器中添加了该块，但没有任何内容显示。为了进行探索，我将 Discourse 块添加到了帖子中。在预览中，它显示了“立即加入 Discourse 对话”，但没有任何评论（Discourse 帖子有一条回复）。
我现在已禁用该插件。
这生成了一个 WordPress 严重错误（下面粘贴了跟踪信息）。我们服务器上的信息：
WordPress version 6.8.3
Active theme: OEG Main (version 0.1.9)
Current plugin: WP-Discourse (version 2.5.9)
PHP version 8.3.19
跟踪报告返回。
