Digest e-mail is showing 0 on all fields

[Systemedic]

Hi,

I am having some trouble with the digest e-mail which is send daily and show information about the amount of invoices send, closed tickets, overdue terminations and so on. I get the mail but all fields are set to 0 (zero). The actions however take place because invoices are being send out other actions are also in place. 

The daily domain sync is also always empty. 

Does anyone have any idea what can be happening here and how I can fix this?

Regards,

Rob
