I have a shopify e-commerce website and would like to use paypal express checkout as my only payment gateway. I have had good traffic and it seems like I've had quite a few customers reach the payment page (based on Google Analytics) but haven't had any sales yet. I thought this was quite odd so I decided to set up another paypal account to test the gateway. When I tried to make a purchase, the error below appeared which makes me think paypal isn't working. I just followed shopify's instructions to set it up (https://help.shopify.com/en/manual/payments/paypal/set-up-paypal#testing-paypal).
Please can someone assist me, I am spending alot on marketing but seem to be missing out on potential sales. My website is beingbagley.com
Thanks for the assistance, I really appreciate it.
