What happen

• Collection not deleted successfully

• Although it disappears from the screen, the PHP file etc. of the target collection is not deleted on the storage, and it will be displayed again when the page is refreshed.

• There is a difference in the display of the /collections submenu when it is successfully deleted and when it is not. example below.

  • NOT delete correctly.
