});
//--></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?
