Browser cache & compression settings not working?

Hello. Hummingbird's tells me that compression & browser cache are not working, but I know the server is ok and the htaccess file is updated. The performance test tells me that browser cache & compression are ok though. So how do I fix the errors on the browser cache settings page and compression settings page?
