Ah thanks
I saw the joomla reference but because nBill was reporting it I thought it might be nBill making the call. Our techs applied 5.3 earlier today or yesterday I think. I shall reset to 5.2
Your a good un - but you know that
We are now on v2 btw and Ive got our PDF invoices working again

. Even though this wasnt the reason for it failing originally I have found out today that html2pdf software you use as a plug in doesnt seem to work with https (I know this isnt your code) but by running the admin area in http Ive got it working again
