I am also having a similar issue. When comments are added, the title area of the content item is getting pushed up. I am sure its a stylesheet thing, but I am just too dense to find it.
the link to my page is
www.jaredjamestoday.com/index.php?option...t=blog&id=3&Itemid=4
Notice that the first post has a comment. If you click on the comments button it takes you to the article view with the comments. if you then scroll up to the top, you will see that the title is cut off.
Any help would be appreciated!
