Comment problem

Hmm there’s something wrong with my site.
I’ve installed wp a few days ago and also set up the blix theme. Everything was working okay. Today I’ve changed something in the navigation and sidebar, but there still wasn’t any problem with the comments. Now it is. You can’t see the commentbox en the sidebar is weird to. I’ve ulpoad olded wp files over the newer, but there isn’t any fault. I think that I have to change it in the wp login but I have no idea where, it’s all new for me. I hope that somebody can help me, thanks a lot!
