Hello! I have a client that I’ve installed marketpress on. I had some issues early on, but seemed to have worked out the kinks… until now.
When I do a purchase at http://mqumag.com/backissues/ I can get through all the screens fine. My client however, cannot. I’m on a mac, she is pc, dont’ know if that information is vital or not.
Anyway, she gets a blank screen once she gets to the payment screen. I see things just fine and cannot duplicate her error.
Also, I got this message from paypal:

So I temporarily disabled the IPN notifications until I could figure this out. Any advice?
