Return to Merchant button not working

We are using WooCommerce and after the customer's payment has been successfully taken via Paypal the customer sees a Paypal confirmation page with a 'Return to Merchant' button at the bottom, however the button does not work. In Paypal account preferences Auto-return is off so NOT expecting it to auto-return. 

 

In Chrome's Inspector there is an error in the Console that says: Refused to send form data to 'https://mydomain.com/checkout/order-received/3083/?key=wc_order_5b6c0b0b81314&utm_nooverride=1' because it violates the following Content Security Policy directive: "form-action 'self' https://*.paypal.com https://*.cardinalcommerce.com

 

From further reading I believe a Content Security Policy (CSP) needs adding either to the website .htaccess file or to a meta tag on the return page. Or I see there is a 'WP Content Security Policy' plugin, would that fix it? Anyone else had experience with this CSP error?

Re: Return to Merchant button not working

I am facing the same error after the TLS security has been updated. In sandbox, the payment is successfull but the return to merchant button is not working. There is a console error as it is not allowed to submit POST call form to redirect a 3rd party site. 

 

Please help me on this.

Re: Return to Merchant button not working

This is an issue with Paypal's Content Security Policy.  CSP is a feature of browsers to prevent loading content from domains you don't want content to load from.  Their policy currently only allows this for form actions:


"form-action 'self' https://*.paypal.com https://*.cardinalcommerce.com".

 

They will have to dynamically add the return url to the CSP for the return url from the merchant.

 

Here is the message I got from Paypal:
