since upgrading from stable to 5420 I can no longer change any settings, neither via the web-interface, nor via madsonic.properties.
While they are shown to be changed in the web-interface, the change (default list type, port, etc.) never actually happens and the .properties file reverts to standard settings on every restart.
Also clicking on any of the different list types (alphabetically, top 100, recently added, etc.) just shows an empty frame.
OS is Ubuntu 14.04.1.
