I am setting up the billing module in ispconfig3 on an ubuntu 12.04 server using nginx. Ispconfig3 is working great and I'm making progress with the billing module. The problem I run into is once a transaction is completed on paypal, the url it gives to return to my site is incorrect. It should return you to the success.php page but it leaves out my site url like this: https://_:8080/billing/payments/success.php
Notice the underscore where the url should be. IPN works and the invoice gets marked as paid. Only the return link from paypal is incorrect.
I also noticed that the "cancel and return" at paypal before you finalize the payment returns the incorrect link: https://_:8080/billing/payments/cancel.php
I use the ipnproxy.php, but again that works correctly as the invoice is marked as paid.
What am I missing? Is there somewhere in ispconfig or billing where I need to put the return url?
Thanks for your help.
