[Observium] Billing Module Problem

Hi,

We are running the latest paid version, and turned on Billing last week. The cronjob is running fine but nothing comes up in the web interface?

We followed; http://www.observium.org/docs/billing/

conrtab -l shows;

# Billing

*/5 * * * * root php /opt/observium/poll-billing.php >> /dev/null 2>&1

1 * * * * root php /opt/observium/billing-calculate.php >> /dev/null 2>&1

And we have this in our config.php;

// Billing

$config['enable_billing'] = 1; # Enable Billing

$config['billing']['customer_autoadd'] = 1; # Enable Auto-add bill per customer

$config['billing']['circuit_autoadd'] = 1; # Enable Auto-add bill per circuit_id

$config['billing']['bill_autoadd'] = 1; # Enable Auto-add bill per bill_id

However nothing is being auto added?

So we added a bill manually, and when running the cronjob scripts manually all seems to work fine, but after leaving it for a week (so data could build up) we still see this JpGraph error;

​

Thanks, Andy.
