I had to buy and install new Attach Invoice plugin for a site that I had to updtae from J3 to J5. The url is the development/test site.
After I installed I tried to generate invoice from control panel Hikashop. If I click Shipping invoice it's ok. But when I click INVOICE I get an error:
An error has occurred.

What to do now?
I also see now with testing that only the created order mail is send and not the order is now confirmed.
