EFW 3.0 ntopng historical reports

I have ticked the option under Services | Traffic Monitoring to keep history, but it doesn't seem to do so.

If I change the option in /etc/ntopng/ntopng.conf and uncomment --dump-flows I get an error in the /var/log/ntopng/ntopng.log:

[DB.cpp:129] ERROR: [DB] SQL error: BEGIN; CREATE TABLE IF NOT EXISTS flows ...... string); [near "NOT": syntax error]

After that I get lots of:

[DB.cpp:129] ERROR: [DB] SQL error: INSERT INTO flows VALUES ..... no such table: flows

Not much of a surprise given the first error.

Is there a way of keeping the history so I can get the traffic for an IP over a specified date range?
