E-mail doesn’t get sent

Hey,

I’ve been clinging on the order e-mails as my last to-do thing to launch my webshop this friday. Finally found this amazing plugin as an alternative but arises a new problem. I wasn’t content with the standard woocommerce emails and so I designed a custom one and the friend that has made the website for me put it in the file hosting location to replace it. Everything finally works up untill the moment I want to send the pdf invoice within the custom order mail; suddenly the mails don’t get sent out anymore. Before when it was still attached to the standard “completed order” mail it did work so I’m guessing it’s because something changed in the custom mail and as a result the process gets blocked and not even a mail goes out? Any ideas? I’ve disabled all the other woocommerce mails aside from “processing order” because people pay the clothing instantly and from that moment i want to send a thank you mail which I made and attach the pdf invoice to it.

Thanks in advance!
