I have configured WooCommerce in WordPress and enabled PayPal Standard Sandbox with a client PayPal account email Id.
When I purchase 3 downloadable products for a Total amount of USD 3.25 with PayPal Standard payment gateway, I got this error:
"Things don't appear to be working at the moment. Please try again later."…
I checked PayPal settings, it is attached with bank and credit card.
Remember: As can check its not business account nor I filled "API credentials".

This testing account doesn't need to be attached with bank and credit card.

The developer account provide (for testing):
Once registered your developer account, you will need to create a pair of admin + customers account for one URL shop.
