Check demo install
The demo install set up by Jure doens't have many of the issues that are labeled as bugs in this issue tracker. I believe there is a difference in how the two instances have been deployed. Please check the instance set up for checking bugs and see if you can work out if there are any issues with permissions, ports, webserver set up etc
Also as a note; please do not use the demo server Jure set up. I need to use this for demos. Any troubleshooting as per above will need to be done by investigating the other servers set up for testing.
