Odd lingo on top is messing up site

Hi there,

I am quite new to this blog/website creation stuff and I must have done something odd to have messed up the views on my site. I get this message on top of my blog as well as in the WordPress dashboard/control system sites:

Content-Length: 9478 Content-Length: 9947 Content-Length: 1098 Content-Length: 132239

Any idea how to get rid of this and restore normalcy to my site views?

Thank you very much!
