  <p>2017-09-08 13:31:18 - PP_STANDARD :: IPN RESPONSE: INVALID</p>
  
  <p>We have request good and response somehow is invalid "<strong>PP_STANDARD :: IPN RESPONSE: INVALID</strong>"</p>
  
  <p>so what we have done is commented the line:</p>
  
  <pre><code>// if ((strcmp($response, 'VERIFIED') == 0 || strcmp($response, 'UNVERIFIED') == 0) &amp;&amp; isset($this-&gt;request-&gt;post['payment_status'])) {
  </code></pre>
  
  <p>Open Cart after the payment is done changing status to Payed, but is kind a hole in a code.</p>
  
  <p>May be you guys already had the same problem and somehow fixed that ?</p>
  
  <p>Thank You</p>
