Hi Brad. Thanks for your patience.
I just went back through our lengthy email conversion and debugging of this issue as it exists on your installation. I don’t have any new information on the issue yet, very sorry.
As I said before, s2Member is not yet integrated with Pitch Plus Upsells. Thus, any issues that you are having with this type of integration are most likely attributed to the fact that s2Member has not yet been integrated with this particular aspect of ClickBank’s offering.
I’m marking this thread in our TODO list though, and I’ll be sure to update you as soon as s2Member supports this feature that you’re attempting to integrate with.
In the mean time, I would suggest that you take a closer look at the log files we went over before, and see if you can determine why ClickBank is not passing through the “s2 Vars” that I mentioned. Upon review of your log files, I find that s2Member’s post transaction processing is failing due to the absence of these variables in the IPN received from ClickBank after checkout.
Why is this happening? I can’t be sure yet. It’s possible that s2Member needs to be further integrated with this feature in order to satisfy custom requirements for this scenario. We’ll have more information for you as we work our way through this, and support for Pitch Plus Upsells is added into a future release.
FYI: You will find a list of all avaiable features
that s2Member Pro currently supports for ClickBank here.
