I’m encountering some bugs while using Discourse AI. Here’s the situation: First, let’s look at a correct post to demonstrate that my configuration is not the issue and everything is working as I intended. My site’s base language is Simplified Chinese, and there are 9 other languages available. This “New post test 0 translation” post is normal. [image] However, some individual posts are experiencing issues. For example: This “About ‘Image Library’ category” post. The original post was published in Simplified Chinese (it was automatically published when the category was created). But in the translation results, the original Simplified Chinese has been translated into “zh_CN” again, instead of being translated into English. [image] When I tried to manually add the English translation using the red globe icon, something strange [image] [image] In the dropdown list, I am unable to add a separate translation for English. However, in my global settings, English (US) has already been added correctly. [image] I have disabled the CDN cache and repeatedly cleared the local browser cache. This rules out caching as the problem. My basic configuration can also be ruled out, as the first image shows the correct behavior. I don’t understand why this problem is happening. How can I fix it? My Discourse version is 3.6.0.beta1-dev(b8e86ceb23) The server OS is Debian 12.12 I have tested this locally using the latest versions of both Chrome and Opera browsers. URL for the correct case: https://openttc.com/t/topic/61 URL for the incorrect case: https://openttc.com/t/topic/58

这不是个BUG。因为所有分类的说明（系统创建）的默认语言就是En。无论你输入了什么，默认就是En帖。所以不会触发翻译。

Every post has a detected language done by AI. If you have a post originally written in “Chinese”, by right, the LLM should detect it to be “zh_CN”. You can view the detected language in the regular composer (not the translation composer) next to the :globe_with_meridians: . [example of EN at the top of the post] The detected language is important so that the translator does not unnecessarily translate it to the detected language itself, and translates the post to every other language. I suspect what is happening with https://openttc.com/t/topic/58 is that the detected language is incorrect, can you check?

是的。它被错误地检测为en了，而不是zh_CN。我检查了一下，发现所有的由系统创建的分类说明帖子，都被检测为en了。即便是使用中文写的。新的问题：FAQ页面支持多语言吗？应该在哪里添加翻译？

[画像] 昊毅_周: Does the FAQ page support multiple languages I believe the FAQ page uses the typical I18n keys. You can go to your site’s admin page for site texts @ e.g. https://openttc.com/admin/customize/site_texts?q=guidelines_topic.body to replace it.

好的，非常感谢您的帮助。 [画像] 昊毅_周: 我检查了一下，发现所有的由系统创建的分类说明帖子，都被检测为en了。即便是使用中文写的。我想这是一个确实存在的问题。不知道这种情况普遍存在还是因为我的配置错误。

It could be time related as well. If the categories were created before the site language was switched, the category topic languages could all be English. In that case you can go to the categories topics’ first post, open the composer, and toggle them to be Chinese.

你好。经过我的尝试。我在6分钟前创建了一个新分类：https://openttc.com/t/topic/66 然后我什么都没有做。等待翻译生效。随后我就得到了一个内容是中文，但被识别成en的帖子。 [image] [image] 在这个分类被创建时，我的站点语言100%是简体中文。我的AI模型用的是Openrouter的Llama3.1 8b。

Interesting, can you run this data explorer query? -- [params] -- integer :topic_id = 66 SELECT a.id, a.created_at, a.response_tokens, (REGEXP_MATCH(a.raw_response_payload, '"text": "([^"\\]+)"'))[1] AS llm_detected_locale, a.raw_response_payload FROM ai_api_audit_logs a JOIN posts p ON p.id = a.post_id AND p.deleted_at IS NULL LEFT JOIN topics t ON t.id = a.topic_id AND t.deleted_at IS NULL WHERE t.id = :topic_id AND p.post_number = 1 AND a.feature_name = 'translation' AND a.response_tokens < 5 This should tell us what the LLM is actually returning. If we’re seeing an “en” in the llm_detected_locale column, I suspect your site’s prompts for locale detection may need a change, or you can use a more suitable LLM (maybe qwen?)

您好。我最终没有解决这个问题，但是影响不大。最准确的问题描述应该是：当我创建一个新的分类时，那张由系统自动生成的“关于此分类”的帖子，他的默认语言会被识别成en。虽然他的文本内容确实是简体中文，但当我打开帖子时，他就是会被识别成英文，需要我手动更改才行。我不确定，这是不是和我的app.yml文件设置有关？

FAQページは、通常のI18nキーを使用していると思います。サイトの管理ページでサイトテキストを編集できます。例えば、https://openttc.com/admin/customize/site_texts?q=guidelines_topic.bodyで置き換えることができます。
