Hi @divyasinghinfo,
Thanks for the screenshots and screen recording, they offer additional context here.
It is showing me two paypal option on checkout page.
How to remove two Paypal option?
I can see that you’re using two PayPal gateways: the PayPal Payments and PayPal Standard. Thus, I would suggest going to the WooCommerce → Settings → Payments page then disabling one of these gateways, mostly PayPal Standard.
When I pay via last option of Paypal then it is showing me this error.
Seems the last option is PayPal Payments. Kindly reach the support team here for further checks on this issue – https://www.ads-software.com/support/plugin/woocommerce-paypal-payments/.
Hope this helps.
Thanks.
