Why is the checkout button on my site suddenly not working?

[Hugh304]

The checkout button on our website (www.beautycornerca.com) suddenly stopped working. Items can be added to the cart, but when the cart button is clicked, the checkout button is greyed out and cannot be selected.
The website has been functioning normally until this point, and the product stock has not been a problem. And I tried to settle the payment in multiple browsers, but I couldn't complete it.

How can we fix this?

thanks

The checkout is working without issue. You can always test this by addign some things to the cart and then navigation to /checkout.

In your case I can see a JavaScript error fires when clicking the button. The code is from something called flashify (flashsale.min.js). If this is an app you'll want to reach out to the developer or perhaps remove the app if it's critical enough.
