Return url is not json encoded.
So script cannot read the PHP return URL

\www\includes\modules\payment\stripepay\create.php line 63
add following code
PHP Code:
$jason_confirmationULR json_encode($confirmationURL); 
and rewrite from
Code:
    var confirmationURL = JSON.parse('<?php echo $confirmationURL; ?>');
to
Code:
    var confirmationURL = JSON.parse('<?php echo $jason_confirmationULR; ?>');
if it's OK.
could you reply the post?
