Looks rather interesting doesn't it...sorry have to joke at times to stay semi-sane.

Have you made sure that all your lightbox files are in their correct locations. I notice that none of them open into a light box.

What do you have your setting at in the admin section.

I also noticed that your header image is duplicating itself too.

open the zip and compare the contents to the server files to make sure they are in the right folders ---then as a safe measure reupload them to each respective folder.

sometimes the files get caught up in some ftp vortex that we do not see and appear to upload correctly but really get corrupted a bit.

see if that helps
