Hi for the last two years did we use the invoice pdf. It would send an pdf with the order with our confimation email. A week ago out of nowhere and without us changing anything this just stopped. The email still get send but the pdf doesnt.

We waited a week and updated the website, hikashop everything. However the pdf is still not send. So we looked at our settings and all looks ok. We have no idea what to do now. Any tips?

update, we did read somwhere that the pdf should be shown in this map. we checked and its all empty: plugins/hikashop/attachinvoice/attachinvoice/invoices

OK i just found the problem. We walked true your questions and when we used the print button it gave an error message. (We never use this option.) It couldnt find the logo. We changed the link to the logo and everything worked again.

Thanks for the good help as always.
