"Child node" or "Insert node" errors

This is caused by translation tools. It's a conflict between third-party translation and certain messages.

Includes:

• Browser translation — Chrome's translate feature
• Translation apps and extensions
• Your phone's system-level translation

To fix it:

1. Turn the translation tool off
2. Return to your chat and regenerate the last message
3. Clear your browser cache (desktop) or sign out and back in (mobile)
4. If you want translation back on, re-enable it and test — you may need to repeat this

Use our built-in translation instead. It doesn't cause this problem:

• Chat language: profile settings → Preferred Chat Language
• Site language: the globe icon on the home page

You may need to start a new chat for the chat language setting to apply consistently.
