Yes sorry for not replying to you. I resolved it – yoast seo plugin was creating redirects after category removal – so when I created new one or renamed it yoast created redirect to non existing category.
So now it is working just fine – I just deleted those redirects.
Have a nice day.
Hello there, thank you for replying. I will test it in few day. I let you know how it went. 🙂
For now have a nice day.
As i tried this several times befor this (and i tried it again) it is not working this way.
