Can't find user id 42

Hi, I installed the wedding template and it looks for a user id 42, even though there is only one user (Super User with id 7xx) added.
Where can I get rid of that warning?

Hello,

1) Open your Joomla database using the PHPMyadmin tool (usually, it's available in your hosting panel).

2) Find and open (click “Browse” icon) “#_users” table (# is your database prefix)

3) Find and open (click “Edit” icon) the record with “Super User” name.

4) Change Super User id value to 42 and click the “Go” button.

5) Find and open (click “Browse” icon) “#_user_usergroup_map” table.

6) Find and open (click “Edit” icon) the record with “group_id” value 8, change “user_id” value to 42, then click the “Go” button:

7) Logout from the Joomla admin section and login back.

Regards,
Milos
