Problem

-- When you change the log settings in Policy Studio and press "Apply Changes," Policy Studio does nothing and reverts your changes.

Resolution

* This just means that Policy Studio was unable to save your changes, most likely due to a temporary problem communicating with the instance(s). Make sure that all instances in your group are fully up and try reconnecting with PS or doing a deploy to refresh your connection and then try again. Once it's able to communicate and save the changes, your changes will remain present.
