Error at development of new payment gateway plugin
I'm developing a new gateway from my Classipress 3.2 site.
I'm following all instructions from documentation of the Gateway API (http://docs.appthemes.com/developers...yment-gateway/
But I came across an error!
The error message says that the APP_Gateway is not loaded yet!
But I made this in my plugin like the documentation says to guarantee that the APP_Gateway is loaded:
add_action( 'init', 'my_plugin_setup' );
So, I don't know where is the mistake!
