Subject Re: Preferences->Themes Unexpected Error
Date Thu, 10 May 2007 16:04:19 GMT
Go to the Server Admin page and set the "Handle of weblog to serve as
frontpage blog" that should fix the problem.

But I'm not sure why you are getting that error, the
'site.frontpage.weblog.handle' should not be null. What database are
you using?
