Comments are disabled
POST to a comments API returned that comments are off for that surface. GET may still return an empty disabled list without this error text.
Why this happens
- File download pages: Enable file comments /
toggle.efcoff - Public folders: Public folder comments off
- News: site
news.comments_enabledoff, or the post has comments disallowed
Diagnose and fix
1. Settings → Files — turn on file comments and/or public folder comments as needed.
2. News comments enabled (+ per-post allow-comments) for news articles.
3. Save and refresh the page; try posting again.
4. Captcha and length rules only apply once comments are enabled.
