Problem
When you try to delete a user, you see the message:
"You cannot delete the last user with rights to create or edit users. Grant these rights to another user first before deleting this user."
this message caused by a wrong if condition. It verifies that you should have at lease 2 users with Administrator rights, it means, that you should not see that error message if you have 2 admins, and you delete a non admin user.
Fixing bug steps:
open file App_Code\UserServices.cs
find line 146,
if (adminCount <= 1)
{
return new JsonResponse() { Message = Resources.labels.cannotDeleteLastAdmin };
}
change the if condition from "<=" to "<"
if (adminCount < 1)
{
return new JsonResponse() { Message = Resources.labels.cannotDeleteLastAdmin };
}
wich means that you should have at least one user with Administrator privileges.
