几天前，我将 Discourse 更新到了 v2026.8.0-latest 版本。一些用户的头像变成了默认图片（不是字母头像）。尝试上传新图片没有任何反应。预览显示了图片，但保存后又会变回默认图片。无论是用户还是管理员操作都如此。界面没有显示任何错误消息。
首先，我尝试用 rake 刷新头像，但这没有起到任何作用。然后我检查了日志，查看在尝试更改头像图片时是否有任何显示，我发现了以下日志消息：
图片优化失败：原因未知 upload_id: 位置: {raise_on_error: true, quality: 90, upload_id: 235861} 错误消息: 无法将 Hash 隐式转换为 String 指令: [“convert”, “png:/var/www/discourse/public/uploads/default/original/3X/2/c/2c620efd4ee10548884a11b7237d5aa9135817b1.png[0]”, “-quality”, “90”, “-auto-orient”, “-gravity”, “center”, “-background”, “transparent”, “-thumbnail”, “24x24^”, “-extent”, “24x24”, “-interpolate”, “catrom”, “-unsharp”, “2x0.5+0.7+0”, “-interlace”, “none”, “-profile”, “/var/www/discourse/vendor/data/RT_sRGB.icm”, “png:/tmp/discourse-thumbnail20260730-360984-9yk3a1.png”]
发送文件 /var/www/discourse/public/images/avatar.png (0.3ms)
所以，我猜测处理图片优化的代码中存在类型不匹配的问题。
有趣的是，我也无法在这个论坛上上传头像，怀疑这里也发生了类似的事情。至少在这里我会收到一条关于“出了点问题”的错误消息。
有什么办法可以解决这个问题吗，还是我只能等待修复？

看起来是 d-topic-previews-sidecar 插件的问题。我会检查一下，并向核心代码提交一个 PR 来修复这个问题。
这确实令人惊讶。我们这里并没有安装那个插件，而且头像上传功能对我来说似乎工作正常。你能再试一次吗？如果出现错误，请提供一张截图，那就太好了！

啊，看来这个插件已经归档，不再维护了（readme）。你应该从 app.yml 中移除它，并运行 ./launcher rebuild app。

是的，在原始仓库被完全删除且无法访问后，我用遗留包替换了原始插件。我尝试移除它，看看是否会有所不同。
这是我在此处尝试上传头像时弹出的错误消息
不过现在可以正常工作了，大概是我这边的问题。
无论如何，我在禁用插件后会再反馈情况。

我在半小时前打开一个主题后收到了这个错误。我没有复现步骤。

我移除了插件，一切似乎又恢复正常了。感谢您的帮助，抱歉打扰了。
