I downloaded a modification today:
Free 9 Invoice Layout Template
https://www.opencart.com/index.php?rout ... ber=aauwwo
After realizing the modification was not working for me, I decided to delete it. I done this by going into the admin panel > Extensions > Modification and deleting. (refreshed cache etc)
After removing the modification, I seem to be getting the below error message when viewing the "shipping list" under Sales > Orders
Code: Select all
PHP Warning: A non-numeric value encountered in /admin/controller/sale/order.php on line 1799
PS I am using the Journal3 theme, so not the default Opencart.
