Hello
Can you tell me why my checkout page is not working?
Hey, @claudiu1988 ! Welcome to Shopify Community!
It appears that you’re viewing your product page through the preview window. The checkout isn’t available when you view a product through the preview window, that’s why you’re unable to access it. In the product page in your admin, you can try clicking Share > Copy link instead of View, as illustrated below, so you can access your website through the storefront. Once you’ve copied the link, you can paste it on the URL bar of your browser. The checkout will be accessible there.
Let me know if that works!
