Lightbox Gallery stopped showing new photos or updates

I have Lightbox gallery installed on this site http://ecoart1.lindsayseligman.com/new-world/

For some reason it has stopped showing updates of new photos or rearranged photos on my page. I have no idea why. The change shows in the edit gallery box when I open it and it shows in the code for example there are 3 photos that I can see on my page but the new 4th on I added is in the code but wont show on the page. [gallery ids="480,479,757,505"].
