Klarna Payments – Known compatibility issues
Here we gather the plugins that have known compatibility issues with Klarna Payments for WooCommerce. This document will be updated if/when needed and it's our goal that the list will shorten rather than expand.
Some of the plugins listed below may have a solution; others unfortunately do not. We always try to make our plugins compatible with as many other plugins and set-ups as possible, but depending on code outside of our control in other plugins, we can not always enable compatibility.
It is a known issue that enabling Conclusion of Contract in Germanized's Manual contract option will result in Klarna's confirmation page being missing after a customer completes a purchase in Klarna Checkout and Klarna Payments.
If this feature is activated, clicking Buy now to complete the purchase on the checkout page, the customer will be redirected to a confirmation page where they're asked to accept terms and conditions and make sure their billing and shipping information is correct before they can proceed to completing the order. Clicking on the button Place binding order to complete the order will redirect the merchant to the checkout page again. This is repeated forever, trapping the customer in a pay-confirm loop.
Bad value: order_lines.total_tax_amount
Solution: Use the standard WooCommerce tax options to add the new temporary tax instead during the temporary time.
If this option is enabled, Klarna Payments won't be able to display on the checkout page.
Error: I can not see the Klarna Payments payment way in the checkout and I'm using WooCommerce Blocks and their Checkout Design Widget.
Solution: WooCommerce Blocks got a Checkout Design Widget that is causing this as it is ONLY compatible with these payment gateways.
The solution is to use the shortcode widget instead and use the standard WooCommerce shortcode
Error: For some reason the product filter script runs on the checkout, and because an anchor tag / link is used to produce the 3DS bank authorization form, it causes the checkout to reload.
Solution: Within the plugin, go to Advanced, then scroll down to Init plugin on the next site pages only (this allows you to list the site pages where you want the script to run. Leaving it empty means the script runs on all pages). Enter one URL per row. Click Save changes.
