Checkout is currently failing on my WordPress + WooCommerce store whenever a customer reaches the Clover payment step. The charge never completes and WooCommerce logs show a generic “payment gateway error.” The job is to trace and eliminate the root cause, whether it stems from the Clover gateway plugin, API credential issues, theme or plugin conflicts, or server-side misconfiguration. I’m running the latest WooCommerce with SSL in place. What I need from you • Pinpoint the exact error and explain it in plain language • Apply a clean fix (code, settings, or server tweak) that survives plugin/theme updates • Prove success with at least one end-to-end test order on staging and one on the live site • Provide a concise change log so I can replicate the solution in future environments Familiarity with WooCommerce payment hooks, REST API logging, and the Clover gateway is essential. Once the checkout flows smoothly again, the project is complete.
