We have worked out the underlying issue that caused the errors, there was a misunderstanding in the office whilst updating the master image last week that has left the settings.php file mistakenly in place. @martin had the same issue here: Brand new emonPi emonCMS not working - #9 by SJM81
We will be emailing everyone who has ordered a unit in the last week to offer either a replacement SD card or for those confident in a little SSH the steps to fix, which are:
1. Enable SSH using the push button to scroll through the emonPi menu then press and hold on the “enable ssh screen”
2. Connect via SSH using putty, download here:

host: You will need to enter your emonPi’s IP address, as soon on the LCD
username: pi
password: emonpi2016
3. Once you are connected, execute the following command
sudo rm /var/www/emoncms/settings.php
then reboot the emonpi
sudo reboot
