Dan,
I figured out your problem.
You should not put <appSettings> under <communityStarterKit> section.
The following format is incorrect!
<communityStarterKit>
......
<appSettings>
.....
</appSettings>
</communityStarterKit>
Should be:
<appSettings>
.....
</appSettings>
<communityStarterKit>
....
</communityStarterKit>
The full web.config should be:
