post title moves when viewing in a single page

Hi there,

I wonder if anyone can help me resolve an on going problem…I HOPE SO!

Here is my site…
http://www.thevintageshowroom.com/blog/

When the post title, or ‘read more’, is clicked, the post is show in a single page. This is great but for some unknown reason the post title and the date shift out of place causing a rather ugly display… I wish them to just stay in place, as they are seen on the blog home page…

Many many thanks in advance for any help…

Nic.
