Memorandum for yourself
Delete the administrator from the administrator list screen Then the following error appears on the browser.
Unknown action The action 'show' could not be found for Administrator::AdminsController
Comes out. Why show ??
I checked controller, view, and path, but there was no problem.
If you check the error log on the web developer console,
Confirm that an error has occurred in the bootstrap-form module.
After checking the operation, it was successfully deleted.
