I'm using PMPRO 1.5.9 and WordPress 3.5. We have Paypal Standard setup, but no matter what payments don't seem to be communicated back to the plugin that they have gone through. The Paypal payments go through, but the user is simply set to no membership level on the website. They are only set as a subscriber in WordPress with no level and no payments get communicated back to the site that they've gone through.
When I try to access the confirmation page it always redirects back to the home page of the site. This is the site I'm referring to:
I have setup a Paypal sandbox account and everything happens exactly the same. Payments on Paypal work on that end, but don't get communicated to my website and no payment information is received by the plugin. I have setup the IPN handler on Paypal. Is there something we're missing? Any assistance you can provide would be appreciated.
