Cannot make paypal payment
I have this dummy store: http://pipingtech.store/yourQuote.php. I'm trying to proceed with a 50cent payment via Paypal. I get to the payment options screen in Paypal, select the method of payment, and press the "Continue to Review Order" button. But this takes me back to an empty shopping cart. Any help here?
Also, the checkout screen is not responsive. Is that supposed to be the case?
