The account registration system is not working well

1) There is a CORS error that prevents the registration from proceeding...

2) my wife went to create her account and apart from the first error, she has placed the credit card and they have deducted 1 dollar several times, but she does not complete the registration!

She always happens something, or fails due to the CORS error or tells him that there was an error with the credit card, which is not true, he even deducted 1 dollar several times and then returned it !!

what's going on? my lady needs to create the account to purchase an instance!
