My website’s contact form no longer delivers messages. Instead, it throws an error every time I hit “Send.” Messages never reach their destination, even though the form is wired to a custom SMTP server. I need someone to: • Identify the exact reason the form fails on submission and shows an error • Correct the mail-sending logic so every valid submission is delivered reliably through the existing SMTP credentials • Confirm success with a short test plan (at least two successful test emails that I can verify in my inbox) You will have access to the current form files and the SMTP details once we start. Please keep any code changes clean, documented, and limited to what is necessary to resolve the issue so future updates remain straightforward.
