In WordPress, when you create a main category and create a category as its child, connect some articles to the child category and then open that category, you will see that article in the list of that category. 
So far no problem and everything is working properly. 
Now, if you add a word in the browser address between the main category and the child category, it will still display the same list if that category does not exist and it should be referred to the 404 page.
example.com/parent_category/child_category/ —> post1 , post2 
example.com/parent_category/random_text/child_category/ —->post1 , post2
after install
example.com/parent_category/child_category/ —> post1 , post2 
example.com/parent_category/random_text/child_category/ —> 404
With this plugin, this problem will be solved and a 404 page will be displayed for addresses that do not exist. 
This problem will be very useful for colleagues who work in the field of SEO.

Tired of uncategorized posts? Use this simple plugin to require users to choose a post category before updating or publishing a post. By default this only applies to normal posts. If you wish to require a category/taxonomy for a custom post type see the FAQ for filter hook usage examples.
