We are working in a new website and having issues with duplicate categories slugs from "posts" and "pages". We are trying to develop the same structure of this website: https://coconuts.co.
We started with the News category:
1) We tried with nested categories without success. The problem is that when we create the child category "news" for the second city, Wordpress set automatically the slug to "news-2". This seems to be the Wordpress behavior by default.
2) Then we tried with Custom Posts Types. After installing the Pods plugin, we created "City1" and "City2" custom posts types with "city1" and "city2" as their slugs. Then we created for them their own category "news" and its child category "politics".
When we visit City1 and News pages everything works fine. We can see the web page and the custom posts inserted in them. But when we navigate to the third level "Politics" page, wordpress can't found it.
There is a chance that Coconuts use a Multisite wordpress installation, but we would like to obtain the same structure in a single wordpress installation.
Any help will be appreciated.
