Error after upgrading from 4.2.11 to 4.3

1. Ran upgrade check -- removed all plugins that were incompatible

2. followed upgrade procedure:

(running Centos 6.3, in a VM)

After upgrade finished:

Please wait a few moments while Confluence starts up.

Launching Confluence ...

Installation of Confluence 4.3 is complete

Your installation of Confluence 4.3 is now ready and can be accessed via

your browser.

Confluence 4.3 can be accessed at http://localhost:8090

Confluence 4.3 may take several minutes to load on first start up.

Finishing installation ...

root@confluence ~ #

Tried the main page, got the normal front page, but when trying to login we get this error:

Content Encoding Error

The page you are trying to view cannot be shown because it uses an invalid or unsupported form of compression.

Please contact the website owners to inform them of this problem.


Luckily since it was a VM I reverted to a snapshot taken just before the upgrade. This symptom is repeatable.

Hi Gerard,

It seems that you are using the confluence installer to upgrade the application. I recommend to upgrade confluence manually since the installer can be defective sometimes. The manual installation can be way more reliable.

if the issue persists, maybe you could attach the latest confluence logs to this question so we can check that.



Hi Gerard,

After you upgrade to 4.3, please stop Confluence and delete all contents inside <install folder>/work after that try starting Confluence again.

Best regards,

Felipe Alencastro
