Hello,

it seems that your problem is a bit different from the one discussed in this thread.
If the sitemap includes the link: /cms/component/content/article/2-contentpages/93-xyz
it means that the article 93 has no menu item linking it or the containing category. So the Joomla router can't resolve its alias.
This should be solved for example creating a menu item (even if hidden) linking the article or the category.


Of course you could even go for the solution of the menu item of type 'External URL' using an hidden menu. In that case the link must be absolute: http://www.yourdomain.com/cms/category1a/category1b/2-contentpages/93-xyz
and the data source for the hidden menu must be published and must have the option to include 'External link' in the sitemap flagged as enabled.
