Thank you for reply, Klas. I know how to build a link. I also think to understand what „/parent/alias“ mean. But i get some 404 errors with this route i can not solve, so i thought (+) could mean only work with special plugins or so.
I Have a list and search view (category) and display two list modules with articles they are linked content -> view. Both modules uses same list/search type, with override art_catid to show different content. The Links on on the one module does work well, on the other module all links result in „404 – component not found“. Both selected categories are siblings, enabled, same type, articles are published and so on – I can not found any difference on settings.
On some other pages and lists i get error 404 – Category not found. There would be no error with router „/alias-id“.
Any hints for me? (:
