Hi Kyle,
Further work by our developer found a "bug" in the CB Subs code.
The developer's description is as follows: "It was a CB paid subscriptions bug. We have checked the code of this plugin (see the file: components/com_profiler/plugins/user/plug_cbpaidsubscriptions/libraries/cbpaidWeservices.php), and have added a change in the 116 line (please see the snap in the attachment: we have added "/" after $urlParts[0]). The problem was, that the plugin has incorrectly generated the URL to eWay. It seems, that CB-subs works correctly for PayPal (i.e. generates the right URL to PayPal). However, for eWay an adjustment in the plugin code was necessary."
Regards,
Robert
