I don't know where the Jreceiver logs would be.
Jetty log shows.

17:00:32.309 EVENT action: ERROR: failure in SettingEditAction, http://localhost:8080/trio/RPC2

The mysql log file posted previously shows no sql error.

I am still running alpha4 as alpha5 still shows the error I posted previously.

Trio is useable as it is, but I am happy to help any way I can.
