Our referral form is throwing the message “Your submission failed because of a server error” every time someone hits Submit. The form includes standard contact fields, a service selector, a file-upload component, and Google reCAPTCHA, so the problem could sit anywhere between the plugin settings, SMTP/email configuration, file-handling routine, or the server itself. I need you to trace the exact cause, correct it, and verify that the form now sends or stores every submission without errors. Once it works, give me a short note outlining what went wrong and how you fixed it so we can avoid the same issue later. The job is urgent—I’m ready to grant access as soon as you’re available and would like to see the form functioning properly right away.
