php exec() issue

[h2d]

Hi

Am trying to activate cacti on my server but i get this error

Notice: Undefined variable: snmp_value in /home/admin/domains/domain.com/public_html/cacti/lib/snmp.php on line 119

Warning: exec() has been disabled for security reasons in /home/admin/domains/domain.com/public_html/cacti/lib/snmp.php on line 119

Notice: Undefined variable: snmp_value in /home/admin/domains/domain.com/public_html/cacti/lib/snmp.php on line 131
SNMP error

This generally means, safe mode is on

I have turned off safe mode as well as open base dir.

Still have the same problem, and i also confirm that safe mode is turned off for that domain with phpinfo.

Cacti use to work, but no longer does ??

You have to compile snmp into php and enable the exec function.
