I enabled debug to see why I was only getting a blank page after a successful transaction on CCBILL

In testing the CCBILL plugin I get these errors going to the postback URL: http://www.example.com/billing_ccbill/order/postback/

did anyone else have problems with this plugin? CCBill support confirmed all is ok on then end. Just been waiting on the developer for support... but thought I'd ask here too.

Thanks
