which clearly shows that the extralinksbox does not have all its divs closed (unlike the info box). It is possible that both of them were missing before. Even if only one of them is missing now, it will still malfunction as you see.
Try adding another </div> in that line
$content .= '</div></div>';
and see if that helps. If not, there is a problem in another file too.
