My form always worked and now it gives me an error. I never changed the code. I´m using this for years. Its very strange.
These are the 2 files, if someone could help I would really appreciate
Main Code
Send form
When I click the send button gives me this error on the top of the page in the end of the url ?erro=email. I´ve tried to edit the form, since I don´t work with php for long time and its not working still. 
Thank you in advance.
Can you tell us what the actual error message(s) is?
NogDog On the form just doesn´t let me send it to my e-mail like it used to do. And on the url in the end comes something like this www.url.com/form..php?erro=email
well for example the same happens on my e-mail and all was working fine, the error that happens on e-mail is:We encountered an error while sending your e-mail
would be this a server issue?
rocknrolla83 would be this a server issue?
Probably:
$sent = mail($to, $subject, $message, $headers) ;
if($sent)
header("Location: ".$_SERVER["HTTP_REFERER"]."?sucesso=email");
else
header("Location: ".$_SERVER["HTTP_REFERER"]."?erro=email");
IIRC, many mail servers require that the "From" header be a valid email account on that site; so if, for example, your email address there is "rocknrolla83@example.com", you could see if changing the headers to something like this helps:
$headers = 'From: rocknrolla83@example.com' . "\r\n" .
'Reply-To: . $_POST['email'] . "\r\n" .
'X-Mailer: PHP/' . phpversion();
