I made a menu entry linking to the article. But then the URL in the sitemap looks like this:

/cms/xyz

But, as I said, it has to be:

/cms/category1a/category1b/2-contentpages/93-xyz

Otherwise I don't have a specific module visible (which is a menu on the left side).

When I create an absolute external link (invisible, but inside JSitemap published menu, external links are activated), the result is as mentioned before:

/cms/component/content/article/2-contentpages/93-xyz

Maybe my problem is unsolvable within JSitemap and I have to change my site in a way that the URL /cms/xyz displays my side-menu (the module)?

EDIT: I solved it! It was my fault. When adding a menu with an external link (and an absolute URL) the correct entry appeared in the sitemap. BUT there was still the old entry, which I had to deactivate in the "Content" data source.

Thanks!
