Why does my Shopify store say “Checkout is temporary unavailable” to customers?

This error occurs when your store’s primary payment gateway experiences api handshaking errors, when custom shipping zone variables are left unconfigured, or when your store is undergoing background domain verification.

“Most minor website breaks are caused by simple script conflicts, legacy code blocks, or broken API handshakes. We identify and clear these issues immediately as a straightforward, one-time fix.”
