I have found that config.php issues caused blank screen. Try restoring default, then moving in your specifics a few lines at a time.

Cheers,

We are currently running:

I navigated to the /opt/observium directory and ran:

svn update

This succeed then I proceeded to run:

root@observium:/opt/observium# ./discovery.php -u

Observium 0.14.11.6003
Discovery

PHP Fatal error:  Call to undefined function print_obsolete_config() in /opt/observium/discovery.php on line 48

At this point everything seemed fine so far as logging in, the graphing etc. I then rebooted the server for good measure. When it came back up, I could hit the login screen and authenticate, but beyond that, a blank screen. Any ideas?
