I dowloaded and installed Octoprint from octoprint.org here.
I edited the octoprint wpa file using Atom to add my WiFi network.
I can ssh into the octoprint Pi but when I enter the IP address "192.168.1.xxx" nothing happens, well at first I got an "Octorprint is still loading" and then a message to look at the log files.
I removed the USB WebCam and USB Keyboard Dongle and rebooted - same problem.
Octoprint version: octopi-stretch-lite-0.15.1
Here is the output from the log:
