[PAYPAL PRO] OpenCart 1.5 - "Please Wait" Issue

rwenve wrote:I have been trying to figure out why this keeps spinning "Please wait" and I think I have narrowed it down to this ajax call

<script type="text/javascript"><!--
$('#button-confirm').bind('click', function() {

type: 'POST',
url: 'index.php?route=payment/pp_pro/send',
data: $('#payment :input'),
dataType: 'json',

$('#payment').before('<div class="attention"><img src="catalog/view/theme/default/image/loading.gif" alt="" /> <?php echo $text_wait; ?></div>');
},
success: function(json) {
if (json['error']) {
alert(json['error']);

$('#button-confirm').attr('disabled', false);
}

$('.attention').remove();

if (json['success']) {
location = json['success'];
}
}
});
});
//--></script>
I dont really know JSON but does something need to be installed or turned on in a config file somewhere? In order for it to remove the spinning icon its supposed to at least alert me to errors. I thought it would be easy to test so in the form I didn't fill out any of it and there was nothing returned (error message) - so it's like JSON isnt functioning? Anybody think that sounds logical and can help me?
Thanks

Did you ever find a solution for this? I am having the same issue. It usually happens when the Ajax response is corrupted by PHP error messages which are also logged in system/logs/error.txt.

PHP Exception: Undefined index: cc_start_date_month in /homepages/41/d400055205/htdocs/vqmod/vqcache/vq2-catalog_controller_payment_pp_pro.php on line 19

because its in the vqmod folder I'm not sure what I should change first.

I deleted the lines in the tpl file that actually ask for the cc start date. (in above comments) Is that throwing this error?
