These are my settings:
MEDIA_ROOT = '/home/e-smith/files/ibays/surftrackr/html/media/'
MEDIA_URL = 'http://www.my_fqdn_domain.com/media/'
ADMIN_MEDIA_PREFIX = '/media/'
Remember surftrackr only run (yet) with a Full Qualified Domain Name, or IP.
Surftrackr not run under subdomain like mydomain.com/surftrackr.
So, if you have a free domain "mydomain.com" add it in your server-manager and choose surftrackr ibay for content of this domain.
Then, access your suftrackr domain with
https://mydomain.comLook at the .htaccess file if you prefer to remove SSL and add a few sme users to surftrackr.
