# Fix draw.io editor problems

Almost every draw.io editor problem is one of five things, and four of them are fixed from the browser rather than in the app.

Work through these in order before assuming something is broken.

## What this is for

* The editor will not load or shows a blank canvas.
* A diagram appears clipped on the left.
* A reload lost unsaved work.

## How it works

| **Action**                | **How**                                                                              |
| ------------------------- | ------------------------------------------------------------------------------------ |
| Editor will not load      | Hard reload the page. Stale cached assets are the usual cause after a release.       |
| Blank canvas              | Try a private window; script blockers and extensions are the common cause.           |
| Clipped on the left       | A known rendering behaviour with certain diagram bounds. Fit the diagram, then save. |
| Lost work after a reload  | Reopen the editor and take the draft snapshot if offered.                            |
| Slow with a large diagram | Hide layers you are not editing, and consider splitting the diagram.                 |

## A few things that catch people out

* A private window rules out cache and extensions in one step, which saves a lot of guessing.
* If it fails in a private window on a current browser, that is worth reporting.
* Broader symptoms are covered in [Troubleshooting](https://help.gocapable.com/diagrams/troubleshooting.html).
