vxFusion

I'm having a strange problem with PDF invoices sent via email. If I manually create an invoice the email sent to the customer with the PDF invoice attached works just fine. However, when creating a service which automatically creates and sends the invoice, the PDF invoice attached to the email is corrupt and won't open. It shows up as being 1kb or less. I can view the PDFs in Blesta just fine, it's only a problem with invoices sent via email that were created from a service. I have confirmed that my temp and upload directory are writable. I appreciate any help with this bizarre problem!

Yes please! Not sure what is involved in writting modules for Blesta.
