Sorry, I didn’t see the point in changing themes and disabling plugins and potentially causing all sorts of problems on my website for something that seems to be an issue with the Paypal IPN setting. I need it ON for s2member, but eShop requires it to be OFF. s2member rewrites the redirect if the IPN is set to something else and thus s2member will work with other plugins that use a different redirect. But it appears eShop will not work with other plugins this way.
So… I decided to use a different shopping cart system that would work with s2member. Thanks for the response.
