V12 Unable to Disable User

Both System Manager and Administrator are unable to disable a user in V12. Changes are possible to their own accounts (permissions, etc) but not possible to a specific user…

Strangely all activity in Activity Log (creation of Sales Order, etc) by that User shows up as Administrator and not with their user name…Could this signify something more serious?

Appreciate your comments. Many Thanks.

Is there any error message you are getting ?
Check if user does not have a role as System Manager

Hi Abhijit. Thank you for taking the time to reply. It is strange - the user is not a System Manager. Even Administrator is unable to disable user.

Is there anyway to disable or reset the permissions for a specific ERPNext user on server using bench command? I tried bench --site sitename reset-perms
