Bringing the theme up…

Ok you can look first to see what I mean : (look how close to the top the blog is, then click forum and see how the forum is all the way at the top and the blog isn’t)

Im trying to figure out why it drops my blog down a line or two before the theme starts up, even the red cross button at the top doesn’t reach the top. I checked and cant find anything that seems the reason to me. Can someone help?

I have my own modified version of the bligblog theme.
