Alright. Then the error must be somewhere in the server config or in your .htaccess file. Since I don't think you have access to the server config and if it was that broken for all users, your host would have fixed it already, I assume the problem is in .htaccess. What do you have in that file? The recommended setup can be seen on Manual:Short URL.
