PDF download error

Problem is that the plugin doesn’t handle special characters like coma in the product-name to create the filename. It usually works in Safari but not in Chrome.

I added in functions.php following lines to fix the issue:

$file = trim( str_replace( ' ', '-' , trim($doc_title) ), '-' );
// raskin 20160422  ERR_RESPONSE_HEADERS_MULTIPLE_CONTENT_DISPOSITION
$file = html_entity_decode($file);
$file = trim( str_replace( ',', '-' , trim($file ) ), '-' );
