Thank you.
I saw Tools > Logs: Module tab.
I attach a figure.
"Success" is displayed.
However, Output has the following display.
{"package":[]}
Does this indicate that I am not using "Root" users?
I am a Cpanel reseller, so I can not possibly use "Root" users. ( Am I wrong? )
Originally, I think whether selecting "Standard" or "Reseller" is an item of "CPANEL Package".
I also examined ACL.
ACL https://documentation.cpanel.net/display/DD/Guide+to+WHM+Plugins+-+Access+Control+Lists
Guide to WHM Plugins - Access Control Lists
Access Control Lists (ACLs) limit the features that WHM users can access. Each ACL represents permissions that the root user can grant to other WHM accounts (resellers
Server administrators can define ACLs in WHM's Edit Reseller Nameservers and Privileges interface (WHM >> Home >> Resellers >> Edit Reseller Nameservers and Privileges).
There is not this screen(WHM >> Home >> Resellers >> Edit Reseller Nameservers and Privileges) on my WHM screen.
Should I ask the hosting provider (resale source) for something?
