To change the default URL of a post type, please follow the steps below.


 Go to My Content >>  Edit Post Settings. Search and click Edit for the post type that needs to be updated.




Scroll down, find the URL Permalink field, and update the URL as desired.




Important: Make sure to not have any spaces or special characters in the new URL.


When Saving the Post Type, a message will display to confirm this change: "The URL of this Post Type is being changed from classifieds to brilliant-classifieds. This action will also update the slug URL of all associated posts." 


This means that already created posts showing under the URL  /classifieds now are going to display under /brilliant-classiffieds.
