Return URL Displays Empty Page

Hello Sir, Excellent Plugin. Impressive.

I am still having some issues:

1. After payment i am directed to the correct return URL (http://www.XXXXX.com/globalpay-transaction-response?txnref=8-11473-1463616110&status=failed).

2. I followed the following steps after installing the plugin
– Activated the Plugin, Entered all necessary parameters (MerchID etc)
– Created the Page (globalpay-transaction-response)
– Changed Product Permalinks from Default to Shop Base

After payment the globalpay-transaction-response Page is empty.

Please assist.

Thanks
