For the benefit of the list, I rebuilt my server in the end. I have
found that updating django when installing the dashboard can be
hazardous (not being a python man I could not work out why all of a
sudden pip was installing libraries into /usr/local/lib and that of
course meant other installed python modules couldn't be found).

Thanks for the help anyway.
