Hi Konst, I have the same problem. Take a look on the generated URL for the ppp.approvalUrl. I see (in my case) a encoded URL like "https://www.sandbox.paypal.com/cgi-bin/webscr?cmd=_express-checkout&token=EC-...". The result was a iFrame like yours. After I decode the URL - it work. OT: decode with JS -> https://stackoverflow.com/questions/1147359/how-to-decode-html-entities-using-jquery Viele Grüsse Dirk 🙂
