Do you know what is causing this?

Causing what? You mean the credits? Those are supposed to be there, unless you have permissions to remove them from the software authors. You can purchase a license for php-nuke to remove that stuff, that is, if that's what you were talking about.

Try "rewording" the text a little and removing some of the breaks. It looks like you have too much text and too many spaces between the paragraphs.

That should cause it to line up better.
