After translation no list nor sitemap

Tuesday 04 February 2003 6:19:47 am

After I'd installed the translation files as described in the sdk tutorial, I get an error on the admin page and no list and sitemap is shown. The error says that there's no object found.
I installed the "clean_kernel" again, but there's no change.
It doesn't matter what language is selected or if the translation is disabled.

Any suggestions?
