PayPal Express + OpenCart 1.5.6.4 + IE + Bad Gateway

The file catalog/controller/payment/pp_express.php contains the following code starting on line 1317:

Code: Select all

		if ($this->config->get('pp_express_test') == 1) {
			header('Location: https://www.sandbox.paypal.com/cgi‑bin/webscr?cmd=_express-checkout&token=' . $result['TOKEN'].'&useraction=commit');
		} else {
			header('Location: https://www.paypal.com/cgi‑bin/webscr?cmd=_express-checkout&token=' . $result['TOKEN'].'&useraction=commit');
		}
Note the invalid characters in the URL. The URL should be

Code: Select all

		if ($this->config->get('pp_express_test') == 1) {
			header('Location: https://www.sandbox.paypal.com/cgi-bin/webscr?cmd=_express-checkout&token=' . $result['TOKEN'].'&useraction=commit');
		} else {
			header('Location: https://www.paypal.com/cgi-bin/webscr?cmd=_express-checkout&token=' . $result['TOKEN'].'&useraction=commit');
		}
On my OpenCart store, this problem hasn't caused an issue (with IE) until recently. (I assume it is because Microsoft released a patch for Internet Explorer that handles the URL differently, which causes an issue with PayPal.)

In Internet Explorer 11, when a user clicks on the Pay with credit or Visa Debit card button on the PayPal page, PayPal displays:

502 Bad Gateway
--------------------------------------------------------------------------------
nginx/1.6.0

The issue does not show up for Google Chrome nor for Firefox.

Changing the code as mentioned above resolves the issue for Internet Explorer.

That code is not in any core file I that I can see. Perhaps it was something with the way you uploaded the file?

Qphoria, thanks for replying.

I downloaded OpenCart 1.5.6.4 again from http://www.opencart.com/index.php?route ... d/download and extracted catalog/controller/payment/pp_express.php.

The file size for pp_express.php after extraction is 82,317 bytes which matches the file size in the ZIP archive.

I opened pp_express.php using 3 different editors including Notepad++ and all 3 editors show the same problem code (lines 1318 and 1320).

(I'm not sure that by searching you will find the code. As they seem to be non-printable chars.)

Sorry I didn't look at the obvious version in the title :P
I was checking 2.x
Yes it looks like there was some garbage in the url in 1.5.6.4

yes, it's corrupted, in the default 1.5.6.4, up to today ! It has been fixed, in OC v.1.5.6_rc,
but unfortunately, this well-done RC-Release has been KILLED, with all it's fixes made, in favour of OC-2, I assume... :-\
