I've performed a brand new, clean install of Confluence 4.1.2 and it breaks immediately when I click on the link to view Demonstration Space.
The link in question is http://localhost:8090/display/ds which gets redirected to http://localhost:8090/spaces where I'm presented with a 'Page Not Found' page.
I've attached the log file, as I have absolutely no clue why it is doing this. It seems to break during execution of code in the Spaces Directory Plugin, and seems to also be complaining about a missing session and lazy initialization that has failed.
If anyone can help with this, it would be very much appreciated.
Thanks, Ray.
