I have created a sandbox merchant but when I attempt to access my sandbox account through my Wordpress website to make PayPal standard payment, I get the following:
Tried to test with Sandbox but Paypal shows “Things don’t appear to be working at the moment. Please try again later.” – return to merchant.
There is no problem with my website, as my colleague has tested on his account and works fine.
I have turned off "block payments from unecrypted websites" as other support topics seem to suggest.
Is there anything else I can look at?
This is in addition to the fact that, despite payment going through fine, the my website isn't receiving confirmation from PayPal that the payment went through ok (despite it working fine on colleague's Paypal account).
