umbraco tried this to match it using this xpath query'/root/*/* [@urlName = "fr"]/* [@urlName = "notre-communaut%c3%a9"]/* [@urlName = "c%c3%a9l%c3%a9bration-du-jubil%c3%a9-dargent"]/* [@urlName = "messages-cl%c3%a9s"]')
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.
This page is intentionally left ugly ;-)
