Error on Checkout: You have passed a blank string for 'card'.

I cant open https://dev.cttjewelry.com at my end ?

I see this

This site can’t provide a secure connection

dev.cttjewelry.com sent an invalid response.

i have same issue?

https://www.challenge-tennis.com

That’s my development site, not accessible to the internet.

I think the blocked frame message is a red herring (not related to the issue).

Here’s a test site you can see the issue on (images might be broken but the site works):
https://www.christophertaylortimberlake.com/staging/catalog/

The website you show has images URL as

https://christophertaylortimberlake.com/staging/wp-content/uploads/2016/04/Mokume-M84b-14K-karat-yellow-gold-14K-rose-gold-shakudo-2k-5mm-domed-1-180×180.jpg

However the correct URL should be minus /staging/ from URL as

https://christophertaylortimberlake.com/wp-content/uploads/2016/04/Mokume-M84b-14K-karat-yellow-gold-14K-rose-gold-shakudo-2k-5mm-domed-1-180×180.jpg

So if you open this Image opens up

Yes, I know, this is a staging site I put together quickly to demonstrate the issue with the plugin. The broken images are not relevant to the problem I am posting about and will be updated shortly.

Can we focus on the error with the Square plugin?

The plugin is in sandbox mode so you can use credit card number 4242 4242 4242 4242, exp date 11/11, and cvv code 123 to test.

@sycookuk,

Make sure while hitting place order button you add all 3 card number card expiry as MM/YY and CVC else try a different plugin.

Thanks

@skycook,

Your site is on SSL but its not 100% SSL as when i open it up in chrome it has the green lock but soon after when page loads Green Lock diappears

See https://imgur.com/a/labvJ the one has green lock is still loading and after page load is complete green lock disappears so get that fixed

Thank you

@jeff Daigle

Can you make sure you have green lock after page loads as https://imgur.com/snQ4C9n on in Chrome ?

Thanks

Sorry, that exp date should be 11/21 (or anything in the future).

Yes, I’ve got a valid SSL certificate and the checkout page is using SSL (green lock).

Still getting the “You have passed a blank string for ‘card’. You should remove the ‘card’ parameter from your request or supply a non-blank value.” message when I click “Place Order”.

You can try it out yourself, here’s a product to add to the cart:

@jeff Daigle

I can see something like on https://christophertaylortimberlake.com/staging/checkout

<link rel=’dns-prefetch’ href=’//s0.wp.com’>
<link rel=’dns-prefetch’ href=’//js.stripe.com’>
<link rel=’dns-prefetch’ href=’//s.w.org’>

Also on your site which should not be in there and i am definite my plugin does not add it there also i found out that JS for credit cards is not working as it should like when i am entering card details it should take space after 4 digits of card which do not happen

Please make sure you dont have jetpack or any caching plugin as that will cause you issues

@skycook

I see your site is including this as well <script type='text/javascript' src='https://checkout.stripe.com/checkout.js'></script>

Also <script type='text/javascript' src='https://js.stripe.com/v2/?ver=2.0'></script> which is my plugin

I also see you are using wp-simple-pay-pro-for-stripe So kindly disable that

Thanks

The dns prefetch items are added by WordPress Core. Just for fun I disabled them, and the problem persists.

Not running Jetpack or any other caching plugin presently.

Did you disabled on christophertaylortimberlake.com ? how i can see the issue

Please make it in test mode so i am able to see issue

Thanks

Yes, I did, but then re-enabled it since it made no difference and I don’t want to give up the performance boost from pre-fetching those resources.

I’ve turned prefetch off again.

As I said above, the site is already in test mode.

You can add the following product to your cart to test it for yourself:

https://christophertaylortimberlake.com/staging/catalog/rings/cuttlefish-double-band-rectangle-opal-ring-2

Use the following credit card info:

Number: 4242 4242 4242 4242
Exp: 01/21
cvv: 123
