[xwiki-users] Trouble with nested pages after upgrade from 5.X version

Hi, Please, I run into strange situation after upgrade from obsolete version 5.4.5 to 9.3.1. Now I have for example following links: https://czwiki2/xwiki/bin/view/Main/Komunity/ https://czwiki2/xwiki/bin/view/Komunity/ Both links are pointing to same page, however I would like to have just one link. Rename or deleting always affect both links. Any ideas how to fix it? Thanks!
