Redmine

I moved a system from 1.3 to latest 2.0 stable version and ran into a strange problem: seem not to be able to render any XML messages.

First noticed it while trying to render list of Projects via REST API

http://192.168.100.6:3000/sys/projects.xml?key=KEY

In the log file I see

Started GET "/sys/projects.xml?key=KEY" for 192.168.100.121 at Wed Aug 01 18:17:43 +0200 2012

Later on I also noticed rendering XML list issues does not work as well..

Would be grateful for any advice.
