Page not showing up

I tried to add a photo onto this page using cornerstone. I was able to upload it and see it in cornerstone. However when I go to the actual website I now am getting this message:

The page you are looking for is no longer here, or never existed in the first place (bummer). You can try searching for what you are looking for using the form below. If that still doesn’t provide the results you are looking for, you can always start over from the home page.

So I can see the page while editing in cornerstone through wordpress but then it is not on the live sight. It was there before I tried to change the photo and now I am not sure what happened.

I am very new to this and I have no idea what I did wrong. Any help??

The page I need help with: [log in to see the link]
