Paypal HSS getting odd response from saveOrderAction()
I am facing a really odd issue where the hosted solution for Paypal is not working.
Upon clicking the 'Continue' button at the 'Order Review' stage of the checkout process an AJAX request to `checkout/onepage/saveOrder` is made, but the iframe is never shown to complete the purchase. The order is saved in the admin, although with the status of 'Pending Payment'.
I assume here that the html section should return the code of the iframe but it's also strange that it's returning `success: false` and `error: false`...So I don't know which it is!
I have tried getting in touch with Paypal support, they tell me they're not receiving any requests and to check the credentials and to reinstall the module. I've checked the credentials & reinstalled the module (also upgraded to 18.104.22.168) and nothings working.
I am sure my credentials are correct as the express option and the non-hosted version both work fine.
