Empty PayPal Error message

[babyewok]

My client received an empty PayPal error message:

 

PayPal response:
->

 

This is on PS 1.5.6.2 and PayPal module 3.6.5 - any ideas as to what caused this?  Successful orders have been placed before and after this error

When debugging the data returned by the curl, I got this error 

erreur SSL3_GET_RECORD:wrong version number

To fix the error, open the file "\www\myprestashop\modules\paypal\api\paypal_connect.php"

Find this instruction 

@curl_setopt($ch, CURLOPT_SSLVERSION, 3);

And replace it by

@curl_setopt($ch, CURLOPT_SSLVERSION, CURL_SSLVERSION_SSLv3);

Thanks a lot jojohn, it worked!

I received two empty messages regarding this same paypal error today. I found this code in paypal_connect.php:

@curl_setopt($ch, CURLOPT_SSLVERSION, defined('CURL_SSLVERSION_TLSv1') ? CURL_SSLVERSION_TLSv1 : 1);

I am using Prestashop 1.6.1.4

Does anybody know what I should change in my case?
