Unfortunatly, my first impressions were not so good….
$ sudo chmod 644 default/
$ sudo chmod 644 default/settings.php
When I changed the permissions back to 644 for default/ and settings.php, going to any link on the dashboard page brought me back to the install.php page. As always, there’s a reason for everything that happens. In this case, the permissions for the folder default/ should be 755, and not 664.
Always remember… WHAT IF AND WHY NOT?!?
