Hello Michael
The gallery used, relies on a proper document structure to find the container to display the gallery.
One of your "read more.." links has broken the document structure on line 387.
BTW, your document says
<?xml version="1.0"?><!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
but it does have lots of validation errors.
you can check your document here
http://validator.w3.org/i am pretty sure once you fix these issues it will be ok.
have fun :-)
