Hello,
I am trying to setup the TransFirst ePay module, I have set it up but when I attempt to make a sale I get the following error:
Fatal error: Call to undefined function: zen_clear_order_id() in shop/includes/modules/payment/transfirst_epay.php on line 370
when trying to access shop/index.php?main_page=checkout_process
I am running 1.3.7 and it was upgraded from 1.3.0.
Any help would be greatly appreciated.
Thanks
