 * Hi all,
 * I have this error on the payment form:
 * `You passed an empty string for 'card'. We assume empty values are an attempt
   to unset a parameter; however 'card' cannot be unset. You should remove 'card'
   from your request or supply a non-empty value`
 * I’ve been reading your [FAQ](http://wordpress.org/plugins/gravity-forms-stripe/faq/)
   section on this titled ‘Why am I getting an ‘Empty string given for card’ error?’.
 * I’ve disabled all of my plugins except GF and GF + Stripe and have switched to
   the default WordPress theme.
 * The test form is very simple, it just has two fields, one for the product and
   the payment card details field and Stripe is in test mode.
 * I’ve added the form to my page via the ‘Add Form’ button above the WYSIWYG editor.
   I’ve also set Stripe to ‘active’ in the form settings. I do not have an SSL cert
   applied to the site yet, do I need to have this for test mode?
 * Many thanks!
