Greetings Evan!

This is the first time I've seen this particular error, but I see at least
one spot in the code that might end up with a null value for the
newSettings object. Do you see any errors in the TDS logs with more details
(threddsServlet logs), perhaps with a stacktrace? Could I also get a copy
of your wmsConfig.xml file (${tds.content.root.path}/thredds/wmsConfig.xml)?

Cheers!

Sean
