- Use the Web terminal and set the sample public page as the default page:
cp /app/code/sample-public-front-page.txt /app/data/index.php
- Fix the require_once path in /app/data/index.php from dirname(__FILE__).'/includes/load-yourls.php' to /app/code/includes/load-yourls.php. Like so:
require_once( '/app/code/includes/load-yourls.php' );
