Causing error with Klarna Checkout

Hi,

this looks like nonce issue

please seach keyword “change_payment_method_nonce” through the Klarna plugin file and show me what you found

Best regards,

Here is what I found:

\klarna-checkout-for-woocommerce\assets\js\klarna-checkout-for-woocommerce.js  (2 hits)
	Line 99: 					nonce: kco_params.change_payment_method_nonce

Hi,

okay , please use keyword kco_wc_change_payment_method

add it into Cache -> ESI -> ESI nonce list , and also enable ESI

after you have done it , please also provide the report number , you can get it in toolbox -> report -> click “send to LiteSpeed”

Best regards,

Keyword added.

Report generated, LGFZPZXU.

Hi,

okay , from report it looks alright

please let me know that goes

Best regards,

Unfortunately we are still experiencing the same issue.
When the “other payment method” button is clicked the page is reloaded but still it is only the Klarna Checkout showing.

now that makes no sense , I just notice the checkout is no-cache after all , so the nonce didn’t even gets cached

I just tested and it seems working fine on me , how exactly do I need to do to reproduce it ?

I just checked again and the issue is still there.
Can i share a screen video with you so you can see what I see?
What email should I send to?

Hi,

please upload it somewhere like Google driver or dropbox , then send the share link to support at litespeedtech.com with reference link to this topic
