We are using Klarna, but it is not showing on the checkout page. We contacted the Klarna support team, and they checked the integration to our website. They told us that everything is well configured in klarna plugin. They advised me to contact you guys to have a look at the compatibility of the plugin and with your theme.
I have disabled some related plugins and used the default wordpress theme but your Klarna payment gateway is still not showing up. This indicates an error on the plugin side or your settings are incorrect. Please check again
