Jon,<br>
Just installed v4. When trying to configure general frontend settings I'm getting errors.<br>
Per error screen info I add " <customErrors mode="Off"/>" in system.web section - so I can see error details:<br>
<br>

<h1>Server Error in '/' Application</h1>

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