This is what happened. While you created the new site you might have tried to open the site using the local IP address. you might have landed on login page of frappe and might have loged in using the administrator credentials and might have created a user before installation of Apps on your site. if the scenario is same as I assume here, then you need to do the following:
- Drop the current site using the command
bench drop-site [your sitename]
- Then go to the site directory using command
- delete the current site using command:
sudo rm -r [your site name]
Then Create another site (can be same name as was deleted)
as follow the tutorial.
