Project description:
"My WordPress site is running an outdated core and several aging plugins, and customers have begun reporting that their payments through Square are failing—sometimes the gateway simply won’t complete the transaction at checkout. I need a developer who can dig into the Square integration, isolate whatever is blocking successful payments, and restore a smooth, reliable checkout flow.

At the same time, I’d like the WordPress core and all plugins brought up to their latest stable versions, with careful compatibility checks so the Square fix doesn’t break after updates. Once the upgrades are complete, run a full round of test transactions in both sandbox and live mode to confirm everything processes correctly and receipts are issued.

Please document the changes you make and note any plugins. A brief summary of the troubleshooting steps and final test results will be enough for me to keep on file." (client-provided description)
