Why is my Shopify checkout button greyed out and unclickable?

Your Shopify checkout button becomes greyed out when a script execution error pauses the DOM load, or when checkout settings are blocked by unconfigured shipping rates, inactive payment gateways, or cart inventory limits.

“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.”
