I am in the process of migrating codeigniter from centos to ubuntu and after moving the files, adjusting the config files, etc, I am getting the white screen of death. Debugging it, the code seems to die in CodeIgniter.php at
$CI = new $class();
where
$class = welcome
I have confirmed the MySQL is installed and running, both in PHP and on the command line. Additionally, I can't find codeigniter complaining about any errors in either my apache error logs or the codeigniter ones at application/logs. This is despite setting the logging threshold to 4 and setting display errors to true.
