hii
I have registered custom taxonomies for Country, State, and City for listings in my plugin.
However, I am encountering a error when trying to add or edit listings via the frontend form. Also, the listing URLs are showing empty spaces. I am still unable to display the country and state information on the single listing page.
Could anyone please help me understand how to properly fetch and display these taxonomy terms on the single listing view and in urls?
i have added edit screenshot in which the field gets deselcted after saving.
url i am getting: listing/country/state/city/transport/test-transport/
