We have been using ZenCart since 2009 and have always had a purchase order option for a payments. We are upgrading to v 2.1 from v 1.5.7c and see that the basic purchase order plugin has not been upgraded in some time. I downloaded the latest version and uploaded via ftp the 'includes' directory (to our test environment) as we have done in the past, on the hopes it might work with the new version -- no surprise -- no luck.
I am looking for someone to guide me, or assist me in upgrading this plugin to function with v 2.1. It is a critical component for our store and we work with municipalities and more than half of our sales are via purchase order.
I know it's a relatively simple plugin, as there are only two files - purchaseorder.php - in modules and language folders.
I would be very appreciative for any assistance. Dr. Byte - I know you assisted with the last version.
Thanks,
JG
