 * I’m really not sure what the problem is. But, customers are reporting 503 errors
   upon check out.

 * Ok, apparently this is the situation: “To accept payments using the new REST 
   APIs and PayPal Mobile SDK, we currently require a U.S. PayPal Business account.
   But stay tuned for more country support. Note that most countries can use our
   Classic APIs.
 * This is the reported problem: “Note: Direct credit card processing is not available
   for you when using REST APIs. Your live credentials are inoperable for direct
   credit card processing for your country but your test credentials are enabled
   for sandbox testing.”
 * So, the question is how to use classic API’s with Express Checkout? Or any other
   solution would be much appreciated.
