Uploads are temporarily under maintenance. Please try again later
Default upload-maintenance message (maintenance.uploadDefault) when uploads are paused for maintenance.
Why this happens
Admin enabled upload maintenance. Distinct from plan/quota blocks (Uploads are currently disabled, Uploads are not available right now).
Diagnose and fix
1. Visitors: wait and retry later.
2. Admin: clear upload maintenance when ready.
3. See Disable uploads if uploads are permanently off.
4. See full-site maintenance articles if the whole site is down.
