I was working on my branch this morning tweaking some CSS when all of a sudden my Drupal site went into a dead mode. I am running multi site mode and the local.settings.php in the individual sites is being ignored on load.
The parent settings.php file is also being ignored on load.
The site redirects to the installation url: http://site.local/install.php
What could have possibly went wrong and how do I go about resolving that?
