Customers unable to pay with PayPal Account or PayPal Cards

An urgent patch to Actinic.pm is needed now. Instructions follow but in addition I have edited files in the major versions available to you if you do not wish to do the patch yourself. Please contact me.

Starting last week, PayPal rolled out changes to their servers. The changes included a change to a HTTP request response header which broke the Sellerdeck PayPal Commerce integration.

Symptoms

Symptoms of the problem include PayPal card fields not being presented when PayPal selected or a pop up error when the PayPal button is clicked.

Solution

The solution is to make 2 changes to one of the Perl scripts. If you are not comfortable with making these changes then we shall be adding patched scripts for some of the recent Sellerdeck versions which can be used if the file Actinic.pm has not been customised. Alternatively you can request assistance from support but naturally this will take longer to resolve the problem.

Open the site folder in Windows Explorer of the site that you need to fix.

Make a backup copy of ACTINIC.pm in your site folder. If there is a problem with the site after making the changes then restore this backed up file and publish to web to fix the site.

Edit ACTINIC.pm in the site folder using a text editor such as Notepad.

If you can use Notepad++ then you will have line numbers as a guide. The line numbers mentioned below are approximate as they will vary between Sellerdeck versions.

There are 2 edits to be performed, the first may not be required in your version of Sellerdeck Desktop.

Edit 1

Search for the following text (around line 940)

flatten($response)

If not found, skip to Edit 2.

You should see

Code:

if ($response->can('flatten'))
{
%reply_headers = $response->flatten();
}
else 
{
%reply_headers = flatten($response);
}
return ($nResult, $sMessage, $sHTTPResponse, undef, \%reply_headers, $sHTTPContent);

Change the code to the following

Code:

if ($response->can('flatten'))
{
%reply_headers = $response->flatten();
}
else 
{
%reply_headers = flatten($response);
}
if (exists $reply_headers{'content-type'})
{
$reply_headers{'Content-Type'} = delete $reply_headers{'content-type'};
}
return ($nResult, $sMessage, $sHTTPResponse, undef, \%reply_headers, $sHTTPContent);

Edit 2

Search for the text (around line 1110)

foreach $sHeaderLine(@arrHeader)

you should see

foreach $sHeaderLine(@arrHeader)
{
if($sHeaderLine ne '')
{
($sHeaderType, $sHeaderValue) = split(/: */, $sHeaderLine);
if($sHeaderValue)
{
$hashHeader{$sHeaderType} =
$sHeaderValue;
}
}
}

Change the code to the following

Code:

foreach $sHeaderLine(@arrHeader)
{
if($sHeaderLine ne '')
{
($sHeaderType, $sHeaderValue) = split(/: */, $sHeaderLine);
if($sHeaderValue)
{
if ($sHeaderType =~ /content\-type/i)
{
$sHeaderType = "Content-Type";
}
$hashHeader{$sHeaderType} =
$sHeaderValue;
}
}
}

Save the file and publish to web.

Check that PayPal payments are working, you only need to check that card fields are displayed and that the PayPal dialog opens without error when the PayPal button is clicked

I have edited files in the major versions available to you if you do not wish to do the patch yourself. Please contact me.
