Thank you for the clarification comrade Foxpup! The problem is i'm not ussing TOR, just opera browser! But still, cloudflare service pops up each time i try to reach their site.

To fix the problem i foud it easier to copypaste the invoice ID into the noscrypt link :
https://bitpay.com/invoice-noscript?id= (YOUR ID)


Example :
let s say you copied this invoice :
bitcoin:?r=https://bitpay.com/i/T8qnej63zHSwNLKtmurLKx
your ID is T8qnej63zHSwNLKtmurLKx.
Result : https://bitpay.com/invoice-noscript?id=T8qnej63zHSwNLKtmurLKx

You should then be able to see the adress and the amount to pay.
