My current site is https://conferences.unite.un.org/athenaknowledgehub/

I have set up other site, URL is https://conferences.unite.un.org/athenaknowledgehub/nadi

This site is setup in another folder called nadi

I am facing currently 2 issues are:

1: I am trying to access url: https://conferences.unite.un.org/athenaknowledgehub/nadi without login and after successfully login it will redirect me to https://conferences.unite.un.org/athenaknowledgehub/nadi/nadi page which is not exist.

2: For the redirect issue, go to Tools on the home page and click on NADI. You are taken to https://conferences.unite.un.org/athenaknowledgehub/nadi/nadi/ rather than https://conferences.unite.un.org/athenaknowledgehub/nadi

Thanks. Regards
