I've written content i want to publish and saved it. i went to the front of my site and though i'd rename two of the top tabs and link it to the new content i created. I'm lost now as I've published, but i get the following error: Page not foundNo umbraco document matches the url 'http://luviesbakery.co.za/petit-fours.aspx'umbraco tried this to match it using this xpath query'/root/* [@urlName = "petit-fours"] | /root// [@urlName = "petit-fours"]')This page can be replaced with a custom 404 page by adding the id of the umbraco document to show as 404 page in the /config/umbracoSettings.config file. Just add the id to the '/settings/content/errors/error404' element.For more information, visit information about custom 404 on the umbraco website.here's the website, please can someone advise me
