[Observium] Missing IPSec traffic graph

Hello, I upgrade from Observium Community Edition 0.16.1.7533 to Observium Community Edition 0.16.10.8128

I followed this simple guide http://www.observium.org/docs/updating/ I followed every step.

Now I cannot see any IPSec traffic graphs on all my Cisco ASA 5505 and 5510s - they were all present before and working great. Any ideas please?
