  Recreating a superadmin account


When you run setup.php you will be required to enter a super user name and password. 
This user will be able to login and modify any domain or setting. Hence, superadmin!.

With that login you can create new superadmins (and you should delete or change the
password of  admin@domain.tld). If that user is no longer there or you didn't use
the .TXT files, you could add another manually from the database. 

In case you forgot your superadmin username or password, you can create a new
superadmin account using setup.php.

If you also have forgotten your setup password, you can use setup.php to configure
a new setup password.
