Hello res13
From looking at the snipet of the log I don't think setting the importTempPath is the problem, it looks like the appliance might have some file system problems as /tmp should be accessible and writable. Secondly the:-
Resource not found: /dashboard/site-settings/appearance/update
error could be another indication that something is wrong. Can you copnfirm the version of the portal and gateway, and can we review the output of the following command on the portal:-
df -h
We might need to raise a support case for you, if so e-mail me your contact details and I can follow up.
