Problem with paypal sandbox IPN

Hi, first of all, congratulations for this plugin. It is the most simple and intuitive I have tested, and I have tested a lot.

I was not able to test complete paypal processing with the sandbox. The web flow with paypal was correct, the return page was right, but the status of the processing is always pending.

I had to debug all messaging, and I found, paypal was not sending back the IPN notifications. Comparing with another plugin, I found that the other plugin used home_url()+”/”+… (extra slash) for the notify_url parameter.
Then I changed your plugin to set
$notify_url = home_url() . ‘/?pay_gate_listener=paypal_ipn’ and it started working.

Is this a configuration issue or it is really a bug?
