From Directory page to home page

This worked for my some minutes ago but not now. I don’t know if I changed something in settings.

I have this directory
https://affiliatesuccess.eu/articledirectory
When I click on pages in above mentioned directory I want to go to this directory pages
https://affiliatesuccess.eu

But now when I click on a page in this directory https://affiliatesuccess.eu/articledirectory/
I go to for example https://affiliatesuccess.eu/articledirectory/about
But I wan to go to https://affiliatesuccess.eu/about.

What should I do?
