Now this one is weird.  I had this happen to me once about a week ago and
could never reproduce it.  Once I refreshed the page everything worked
correctly again.  It makes no sense as it is complaining about a dropdown's
value but all of them are totally static data so I am not sure what it
could have to complain about.  I would try pulling up the page again and
see if it works for you this time.

Few questions:
1. New install or updating from .3?
2. Can you check that /App_Data/settings.xml is owned and writable by your
apache user (www-data if a debian install)
3. Can you check the error log for any errrors (not related to ZeroConf)
