Thread: Error at development of new payment gateway plugin

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' );
function my_plugin_setup(){
include 'my-plugin-gateway.php';
}


So, I don't know where is the mistake!

Please, help-me!
