Subscription widget loads then disappears

[jlprice]

Hi all.

I have created a Subscription on Paypal OK and inserted the code onto a very simple test page here:

https://brit.co.uk/test.html

When you click either button, the Paypal box starts to load up then just disappears.

This is happening using Firefox, Edge and Chrome.

Does anyone have a cure, please? Or do I just need to be patient as I only set this up today?

Many thanks,

Jon
