@maddox That is odd! Usually nothing works or it all works. Can you provide any logs? In particular the PHP logs from /var/log/apache2/error.log.
Are you using OSPi or OS? If your using OSPi can you provide the log files from it? This can be done by running ospi from console: python ospi.py
This used to be an issue on the OSPi before the Dan updated to the latest version. You need to be using OSPi >=June 22, 2013.
