# Document disappeared after saving an edit, with no error shown

**What you are seeing**

A document disappeared after saving an edit, with no error shown.

---

## Why it happens

The save deletes the old attachment first and then uploads the new one. If the upload fails, the failure is swallowed and nothing is displayed.

---

## What to do

Copy the document text before saving a large edit. If it vanishes, re-create it from your copy. Check attachment size and Jira attachment permissions before retrying.

## Limits that apply here

| **Limit**                | **Value**                  | **What happens**                                                                                                                                               |
| ------------------------ | -------------------------- | -------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| Document title length    | 50 characters              | Enforced by the Title input in the editor. The title becomes the attachment filename.                                                                          |
| Large document preview   | About 1,000,000 characters | Read-only previews longer than this switch to a virtualised viewer that renders in chunks as you scroll, so browser find-in-page and similar behaviour differ. |
| Simultaneous image loads | 20                         | At most 20 image URLs are resolved at once, so image-heavy documents load in waves.                                                                            |

## A few things that catch people out

* If the delete succeeds but the re-upload fails, the document is lost and no error is shown. The failure is swallowed.
* Documents over roughly a million characters switch to a virtualised preview, so behaviour such as find-in-page differs.
