# Some Users Receive an Empty or Blank Editor Instead of Page Content When Editing

#### Still need help?

The Atlassian Community is here for you.

## Symptoms

Some users will not be able to edit certain pages. Viewing a page works correctly, however editing the page leads to a blank page. There are no visible errors in the Confluence log.

When attempting to edit the page, the following message may appear in the browser's error console:

GET <address> net::ERR_INCOMPLETE_CHUNKED_ENCODING

To access the browser console:

• Internet Explorer: Press F12 (or go to Tools » Developer Tools) and then click the "Console" Tab
• Google Chrome, Firefox, Opera: Right click on the page and choose "Inspect Element", then click the "Console" Tab
• Safari: Open Safari Preferences, click "Advanced" and tick "Show Develop in Menu Bar". Then, right click on the page and choose "Inspect Element", then click the "Console" Tab

## Diagnosis

The error shown in the browser console indicates that a complete response wasn't received for the URL in question. It's important to identify what users the problem does occur for, and how those users connect to Confluence. In one case, users in one office were accessing a remote Confluence instance via a bandwidth saving device, which compressed the content coming from Confluence. The content from Confluence was already compressed, resulting in a double compression that the browser could not understand.

## Cause

Ensure that Confluence is excluded from any compression systems between the users having the problem, and the Confluence system. HTTP Compression is enabled in Confluence by default, and may cause conflicts with other compression techniques. Ideally, only one compression technique should be used.

## Resolution:

• Exclude Confluence from any compression systems used in your network.
• Alternatively, you can disable HTTP Compression in Confluence, to allow your compression system to handle the compression instead.
