I’m having this exact same error.
Everything worked just fine with WooCommerce v. 1.6.6
But after WooCommerce 2.0 update, all Authorize.net DPM fields disappeared.
The only visible content is the order #, total amount & shipping. (underneath this is where the credit card info input fields are suppost to be, but aren’t)
I’m using YOOTheme’s Catalyst Theme. (I have followed the WooThemes directions for theme compatibility)
Has anyone else experienced this behavior? Even better would be someone who has and figured out why… and fixed it.
Thanks!
