With 3.1.0 same issue as with 3.0.0: pfBlockerNG DNSBL service can not start

Pfosten

pfBlockerNG 3.0.0 never worked as the old version 2.x
removed the old package 3.0.0 - rebooted.
upgraded pfsense from 2.6.0.a to 2.6.0.b
installed pfBlockerNG 3.1.0 - same bug symptoms as before: DNSBL does not start.
