Hi Zach,
The PayPal standard option does not tell us that the API credentials are not valid. But the checkout process does not work.
The error message that displays when attempted to checkout with PayPal checkout says: Things don’t appear to be working at the moment. Please try again later.
And the error message displays when attempting with PayPal standard is: PayPal error (10002): An error (10002) occurred while processing your PayPal payment. Please contact the store owner for assistance.
And the log says: [L_ERRORCODE0] => 10002 and [L_SEVERITYCODE0] => Error
Thank you for your assistance!
