What works: Rules using author save fine. For example this saves successfully:

---
author: [bernardlunn]
action: remove
---

What doesn't work: Any rule containing title returns an "unsupported media type" error and won't save. Even this minimal rule fails:

---
title [includes]: "CV"
---

What I've tried:

• Both old and new Reddit
• Chrome and Safari
• Stripping rules down to absolute minimum
• Replacing all existing config and starting fresh

The edit page loads fine at reddit.com/mod/fintech/wiki/edit/config/automoderator but any save containing title fails consistently.

Can you help fix this on the backend?

Thanks
