You will see from a post made on the CB forum recently (CBSubs Post-Transaction notification error) that we have run into problems testing CBSubs 3.0.0 with the new sandbox.paypal.com security set up, whereby PayPal notifications back to our server are not being validated and are therefore failing. This may well be a server configuration issue, although the relevant domain is working well with the live paypal.com and our hosting service we have not been able to see any relevant error messages on our server in this regard.

So I have two pre-sales questions, please, before I go back to my customer with what could be quite a large invoice in order to upgrade:-

1) Is it likely that the IPN communication errors we are seeing would be resolved by upgrading to CBSubs 4.1.0 or should CBSubs 3.0.0. work successfully with the new security configuration on the PayPal sandbox server?

2) Is it possible to upgrade to CBSubs 4.1.0 but still use CB 1.9.1?

Thanks a lot

1. I am not aware of any IPN related bugs that were fixed in CBSubs 4.x. The issues are more likely related with bad configuration on CBSubs end or even payment organization end.

2. Nope - CBSubs 4.1 needs CB 2.x. (Plus CB 1.9.1 is no longer supported)

So my recommendation is to convince your customer to upgrade their environment to latest Joomla/CB/CBSubs versions and always strive to keep up with future releases. Staying with old versions is a security risk.
