PHP send() suddenly stopped working

Question

My PHP script for sending email suddenly stopped working, it has worked all along and now when i was just trying it out again it instead showed the fault code. I see no syntax errors and im totally stumped.

Anyone who can figure out where the fault is here?

<?php
$namn = $_POST['namn'];
$epost = $_POST['epost'];
$tfn = $_POST['tfn'];
$msg = $_POST['msg'];
$from = 'B&P Contact';
$to = 'xxx@xxxxx.com';
$subject = 'Kontakt';

//message body
$body = "From: $name\n E-post: $epost\n Telefonnummer: $tfn\n Meddelande:\n $msg";
?>

<?php
//When send is clicked, execute function.
if ($_POST['send']) {
   if (mail ($to, $subject, $body, $from)) {
      echo '<p class="wtext" style="color:red;margin-left:25px;"> Message sent!</p>';
   }
 //error if somethings not working
   else {
      echo '<p class="wtext"> Something is wrong, try again.</p>';
   }
}
?>

I also have this code, but this has nothing to do with this not working, i have tried removing it etc. This code is for storing each msg in a database and then printing out the total number of posts in the db each time a msg is sent. (This is just for a school assignment).

<?php 
$conn = mysqli_connect('xxxxx', 'xxxxx', 'xxxx')
    or die('Could not establish connection to MySQL');
    $db_connected = mysqli_select_db($conn, 'xxxxx');
    //
    //
    $sql = "INSERT INTO Epostlist (namn, epost, tfn, msg) VALUES ('$namn', '$epost', '$tfn', '$msg')";
    //
    // Exikvera
    $status = mysqli_query($conn, $sql) or die (mysqli_error($conn));
    //
    //
    mysqli_close($conn);
?>

 <?php
      //Räkna meddelanden i databas
  $con=mysqli_connect("xxxx","xxxx","xxxxx","xxxxxx");
      // Check connection
      if (mysqli_connect_errno())
      {
       echo "Failed to connect to MySQL: " . mysqli_connect_error();
      }
      //
      $sql="SELECT msg FROM Epostlist ORDER BY ID";
      //
      if ($result=mysqli_query($con,$sql))
      {
      // Return the number of rows in result set
      $rowcount=mysqli_num_rows($result);
      //
      echo "<p class='wtext'>We have been sent a total of $rowcount messages.\n</p>";
      // Free result set
      //
      mysqli_free_result($result);
      }
      //
      mysqli_close($con);
?>

The code above also worked properly with the code above just yesterday.

*Form

<form method="post" action="send.php">
   Namn:<br><input type="text" name="namn" id="name"><br>
   E-post:<br><input type="text" name="epost" id="epost"><br>
   Telefonnummer:<br><input type="text" name="tfn" id="tfn"><br>
   Meddelande:<br><textarea name="msg" id="msg"></textarea><br>
