Live download not available for your account
The member tried to open Live downloads (/my-files/downloads / related API) but live download is not enabled for their account.
Why this happens
Site mod Show live download page (toggle.live_download_page) is off and there is no per-user override that turns it on — or the effective check fails for that user. Defaults often leave the site toggle on when unset.
Diagnose and fix
1. Admin → Settings → Mods → Live download page — enable site-wide.
2. Or set Show live download page on that user while the site toggle is off (per-user override).
3. Member must be signed in; guests get a sign-in required message instead.
4. See Live download page / Live downloads monitor for how the feature works.
