title: paypal sandbox not working
body: <p>I am using the PayPal sandbox to make test payments. It was working fine since last 3-4 months. But I see that they are making changes in sandbox design, ways to manage test email accounts, etc.</p>
  
  <p>They have disabled my actual sandbox account and asks me to login using real PayPal account. So I created a new sandbox (<a href="https://developer.paypal.com/" rel="nofollow noreferrer">https://developer.paypal.com/</a>) account using my PayPal account. I imported test emails from my old sandbox account, and started making test payments. But it didn't work. I deleted all my imported test emails, and created some new test emails. But it also didn't work.</p>
  
  <p>I am logged into the sandbox account, try to make a test payment. But it shows me this message everytime. <img src="https://i.stack.imgur.com/JHZyr.png" alt="enter image description here"></p>
  
  <p>I am not getting what's the issue. Need help please.</p>
  
  <p>Thanks in advance.</p>
