I'm getting this:
Fatal error: Call to undefined function AuthNet_Post() in /home/jvdydf5kad9w/public_html/eCart/confirm.php on line 218
I added the include line to the confirm.php
<?php require_once("../WA_eCart/Adv_CO_Scripts/PP_ECO_Authorize_PHP.php"); ?>
and uploaded the file. But still getting it. What am I missing?
