We would like to hide the base slug of one of the custom post type. So we set
Custom Rewrite Slug: /
With Front: False
This cause divi builder could not load properly with ET_builder undefined error in console. Not sure if it’s the correct way to do it. If this is a bug, then clearly need to be fixed.
We reset the setting we set and hide the base slug with another plugin. Thank you for your time.
