This means that the payment didn't succeed, but the ugly error message is from a little bug in the error handling section.
Turn on PayPal error log to see why payments fail or if you did, check the error logs; admin > tools

Reason: OpenCart version 3+ ;D

Thanks!

Yeah I tried fixing the error in logs. I ended up using PayPal standard since it works instantly and it's not limited to paypal registered accounts. Thanks for the help though :)

You can still read the error in the logs, look for LONGMESSAGE and decipher the text ;D
It would be interesting to know what the error was.

The callback from PP is a string that needs to be parsed into an array after which there'll be an actual index for LONGMESSAGE_0 and continue the page creation gracefully.
I had to fix this for all my extensions. Not sure if there's a report on github but Daniel will get to it eventually.

The error is obvious. SSL failed with cURL. Paypal changed their security in response to the poodle vulnerabulity.

Open \catalog\model\payment\pp_express.php
and change in public function call($data) {

Code: Select all

$defaults = array(
				CURLOPT_POST           => 1,
				CURLOPT_HEADER         => 0,
				CURLOPT_URL            => $api_endpoint,
				CURLOPT_USERAGENT      => "Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.1.1) Gecko/20061204 Firefox/2.0.0.1",
				CURLOPT_FRESH_CONNECT  => 1,
				CURLOPT_RETURNTRANSFER => 1,
				CURLOPT_FORBID_REUSE   => 1,
				CURLOPT_TIMEOUT        => 0,
				CURLOPT_SSL_VERIFYPEER => 0,
				CURLOPT_SSL_VERIFYHOST => 0,
				CURLOPT_SSLVERSION     => 0,//new
				CURLOPT_POSTFIELDS     => http_build_query(array_merge($data, $settings), '', "&"),
			);
CURLOPT_SSLVERSION
One of CURL_SSLVERSION_DEFAULT (0), CURL_SSLVERSION_TLSv1 (1), CURL_SSLVERSION_SSLv2 (2), CURL_SSLVERSION_SSLv3 (3), CURL_SSLVERSION_TLSv1_0 (4), CURL_SSLVERSION_TLSv1_1 (5) or CURL_SSLVERSION_TLSv1_2 (6).

Note: Your best bet is to not set this and let it use the default. Setting it to 2 or 3 is very dangerous given the known vulnerabilities in SSLv2 and SSLv3.


Left out completely, option 2:

Code: Select all

$defaults = array(
				CURLOPT_POST           => 1,
				CURLOPT_HEADER         => 0,
				CURLOPT_URL            => $api_endpoint,
				CURLOPT_USERAGENT      => "Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.1.1) Gecko/20061204 Firefox/2.0.0.1",
				CURLOPT_FRESH_CONNECT  => 1,
				CURLOPT_RETURNTRANSFER => 1,
				CURLOPT_FORBID_REUSE   => 1,
				CURLOPT_TIMEOUT        => 0,
//				CURLOPT_SSL_VERIFYPEER => 0,
//				CURLOPT_SSL_VERIFYHOST => 0,
//				CURLOPT_SSLVERSION     => 0,//new
				CURLOPT_POSTFIELDS     => http_build_query(array_merge($data, $settings), '', "&"),
			);

I used this fix for one of my clients, works :)

The error still occurs. I've already tried clearing and refreshing mod. Hard refresh, etc :'(

It's possible that Apache on your server has an old version of mod_ssl
I can take a look if you want.
