Confluence Upgraded - Pages Not Viewable

[Drew Baldock]

We have upgraded from Confluence 3.2.1 to Confluence 4.3.3 as per the suggestion of one of the support representatives. We have pages not loading and giving a System Error with error messages:

Error rendering template for decorator root

ERROR Mon Dec 17 07:00:44 PST 2012 com.opensymphony.webwork.dispatcher.VelocityResult Unable to render Velocity Template, '/pages/viewpage.vm

Hi Drew,

I strongly suspect this issue will be being caused by plugins that haven't been upgraded yet, so I'd suggest that you check those and disable any plugins that are no longer compatible with v4.3.3 as this should resolve your issue.

All the best,
John
