Fix WordPress Contact Form 7

I need someone to diagnose and fix my Contact Form 7 setup on a WordPress site. Right now, any time a visitor hits “submit” an error message appears and the message never sends.

Your task is to trace the cause—whether it’s mail server settings, plugin conflicts, reCAPTCHA keys, or template mis-configuration—then make the form reliably deliver emails to my chosen inbox. Once you’ve sorted it, please run a live test so I can see the success message on-screen and receive the email, complete with all field data, in my mailbox.

Deliverables
• Repaired Contact Form 7 form that submits without errors
• Proof of at least one successful email reaching my inbox
• Brief note of what you changed so I can maintain it going forward

You’ll get WordPress admin and, if needed, hosting panel access as soon as we start.
