如果用户在一个话题中发帖，而该话题的最后回复者是另一个用户，则会出现 500 错误。但该评论仍然会发布。
但是，如果一个用户发表了一个帖子，并且该用户已经是该话题的最后回复者，那么就不会出现错误。
我作为管理员无法解锁话题。因此，可能还存在其他故障。
我知道的就这么多：
- 安全模式（safe-mode）没有帮助
- 在 app.yml 中注释掉 MaxMind 没有帮助
- Ubuntu 已更新并重启
- Discourse 已通过 shell 在昨天和今天重建了两次
- 显然，这里没有发生这种情况
- 标准安装，没有花哨的东西
- 每个人都会遇到——嗯，至少是手机用户，我不知道桌面用户是否会遇到，但因为是 500 错误，我不知道设备是否会涉及
- 错误：
