Hi,
might be an edge case but I'm getting access denied in my log for ipn/signup_pay when Paypal tries to confirm payment. Probably because I'm running an Open Atrium (with Organic Groups) install where anonymous are denied access to content. This of cause results in the payment not being registered by my site. I would have thought the access to ipn was controlled by this module and not the content access rules? What should I do?
