I am using a Site Assist Pro Template, so the easy way to do it (if you have only a basic CSS knowledge) is to open the template. Click on the border of the content DIV. Click the little pencil Icon on the CSS window on the right, a new window opens, goto positioning, at the top there is an option for Type, I just deleted it.
If you have edited the content.css file before you can just open that file and then look for
#outerWrapper #contentWrapper #content {
There should be an option called position, just delete it.
Thats what solved it for me, I have no idea if it will work for you. Just remember to back everything up or get ready with pressing undo if it all goes wrong;)
