カスタム言語に問題が発生したようです（数ヶ月前に Multilingual プラグインを試しましたが、タグにも問題が発生しました）。\n\n1. カスタム言語を ES（スペイン語）に移動しようとすると、以下のエラーが表示されます：\n\n\nPG::UniqueViolation: ERROR: duplicate key value violates unique constraint "index_translation_overrides_on_locale_and_translation_key"\nDETAIL: Key (locale, translation_key)=(es, js.docs.categories) already exists.\n\n\n2. カスタマイズされたテキストをファイルにエクスポートしようとしても、同様の動作が見られます：\n\n\n./launcher enter app\nbin/rake export:translation_overrides\n\n\n結果：\n\n\nrake aborted!\nActiveRecord::NoDatabaseError: We could not find your database: discourse. Which can be found in the database configuration file located at config/database.yml\n\n\n3. 他のユーザーでは動作していた Discourse Translator w/DeepL が使用できません。\n\n4. 信頼レベル（trust_levels）の文字列の更新に問題があります。これも関連している可能性が高いです。\n\n### /logs に以下のログが表示されます（無効化した Location プラグインに関連していますが、問題は継続しています）：\n\n\nNoMethodError (undefined method `custom_fields' for
