Frsh install NAV & Graphite issue

Hi, I see some graphs in NAV and some not. Particularity the Etherports are empty? Sensors tab shows graphs. Graphite on port 8000 works and shows devices and graphs. The only thing I can find in the log is: [WARNING] [pid=526 nav.django.auth] User default denied access to /search/? query=10.100.5.1 Which in my noobie experience with NAV and Graphite i cannot make out what is wrong? I cannot find anything for days now in any google serach on NAV installs.... Cheers Erik
