I have an active but private website that is using the M4 PDF module for custom packing slips. It is working perfect in all order except for one. Trying to retrieve the slip for order #194 shows the following error in the browser:
-------------
Warning: Division by zero in /home2/website/public_html/modules/m4pdf/M4OrderDetail.php on line 194
Warning: Cannot modify header information - headers already sent by (output started at /home2/website/public_html/modules/m4pdf/M4OrderDetail.php:194) in /home2/website/public_html/modules/m4pdf/mpdf/mpdf.php on line 7093
mPDF error: Some data has already been output to browser, can't send PDF file
-------------
+ The problem is only on this order, every other one that I have tried works as it should.
+ I had to change the shipping address on this order per the customer's request. This was handled through Orlique Order Manager
Any thoughts?
