when I test the checkout process, I get the following error
Notice: Undefined property: eCart1_Definition::$WeightUnits in E:\xampp\htdocs\chabuta\confirm.php on line 500
Fatal error: Call to undefined function curl_init() in E:\xampp\htdocs\chabuta\WA_eCart\WA_eCart_USPS_PHP.php on line 127
I just followed the checkout wizard using usps account.
I have no idea what I did wrong and where to look at.
