Im using Marketpress to create a shop on Facebook.
Facebook uses iFrames to display the content.
Im running Markpetpress Multisite with Paypal (sandbox at the mo) Express gateway.
When I click Continue Checkout after entering shipping info, it takes me to the special instructions page (with no gateway radio button options as expected) and has a button that says Continue Checkout.
When you click that button, facebook attempts to load the paypal express page in the iframe, it doesnt load. Just a white page.
if having it detect is too hard, then having every sale on every network site open the paypal page in a pop up regardless if its a shop on facebook.
This is holding up my project :slight_smile:
