Hi @Hanz1X

Hope you are doing great!

If the checkout button in cart does not work, you can try this way:

  1. Head to Admin > Online Store > Themes
  2. Download a fresh copy of your theme
  3. Publish the new, unedited version
  4. Test the cart/checkout
  5. If the issue persists there may be an issue with your chosen theme; to be sure test your store against an unedited Shopify developed theme

I trust you will find that helpful. Please mark it as SOLUTION and let me know if you have further questions about this
