Cart 3 problems

I am using Cart 3 in RW8 with stacks 4 and have very carefully followed the demo and instructions. When I preview with Firefox the shopping cart works properly and will redirect to either Paypal or Stripe pages. However, when I have uploaded the website, although the cart still works properly and will redirect to Paypal, when I try to pay with Stripe the current page goes to white except for the menu but nothing else happens. Can anyone help me pin down the issue please?
Thanks John

I think Cart 3 is a @YuzoolSupport product so maybe they can advise?

Dear Mr. Colwill,

Thanks for your reply Sydney. It’s a large file at 128MB. Do you mean I should send the whole lot?

You can always put it on something like Dropbox and give them a link.

Use wetransfer.com for this.

Please send us a dropbox link. Thank you,
