Hey Mark, It looks like the netlify site newworldcheckout.netlify.app does not exist or is returning a 404 error. Please check to make sure an index.html file exists at the root of the site. You can learn more here: [Support Guide] I’ve deployed my site but I still see "Page not found”
If there is another URL that you are referring to? If so, please provide this information and we’ll take a look!
