Unable to show "Data Query [SNMP - Interface Statistics]"

Data Query [SNMP - Interface Statistics]

If you are having problem with cacti,"No SNMP data returned" (from verbose query in the devices detail)
No data returned while running snmpwalk -v 1 -c public localhost .1.3.6.1.2.1.2.2.1.1
General problems getting Interface - Traffic graphs to work.
Please edit snmpd.conf file in /etc/snmp/snmpd.conf

You will see:
view systemview included .1.3.6.1.2.1.1
view systemview included .1.3.6.1.2.1.25.1.1

then change to:
view systemview included .1.3.6.1.2.1
view systemview included .1.3.6.1.2.1.25.1.1
(Yes, delete the bold "1")

This command will reduces the limits to the pubic group's access using smtpwalk and allows cacti to get the list of interfaces.
