A critical revenue-blocking damage signal.
Customers reach the checkout or booking page—and nothing happens. Payment fails. Forms error out. Submit button doesn't work. People want to buy. They have their card ready. But your system won't let them complete the transaction.
Usually payment processor configuration is broken, checkout code has errors after updates, API keys expired, or booking system isn't syncing with payment.
Usually after website platform updates, when payment processor API credentials expire, after switching hosts, or during high-traffic periods.
Just send the mess.
