Cron Files & PDF Error



Is there any cron files must be define in order to generate automatically the invoices on time?

I enabled the SMTP and selected yes for Attach Quote/Invoice on email?

I have now 2 problems:

  1. the email is empty
  2. does not contain attachment the quote or invoice.

below what I’m getting when I press on send

Error when emailing invoice

I have the same problem and have not been able to find a solution yet. Were you able to find a solution?


I hope we got an answer as I’m still have the same issue since a month.


I checked the to recurring invoices and I set the cron as well.

The problem is still getting the CRON White page while no log or any output but in the recurring invoices there are invoices must be created 2 days ago

Any assist would be apprecaited
