Reply To: How to show paypal button in custom single product page template?

Hello,

Then you would need to ask the PayPal plugin support to provide you with a HTML Code snippet (not the PHP script for the function.php file) which you can add under the Custom Product layout. If they don’t have any right now, then you might need to disable the Custom Product layout and use the default WooCommerce Single Product layout because the Theme isn’t responsible for the Payment button. It is coming from the third party Plugin. Hope you can understand !

Best Regards
