title: Wordpress $cf7->posted_data Missing - no data available to push to sessions
body: <p>Suddenly (I did nothing) my Contact 7 forms (wordpress) stopped working properly.</p>
  
  <p>My functions.php was working with the submitted data - affecting all my forms.
  This is affecting 2 sites I manage and seemed to happen to both at same time.</p>
  
  <pre><code>    add_action('wpcf7_before_send_mail', 'my_conversion');
  
      function my_conversion($cf7)
      {
      $firstname = $cf7-&gt;posted_data["FirstName"];  
      }
  </code></pre>
  
  <p>The problem is that $cf7->posted_data["FirstName"] is blank for some reason - no value.  Yet my form has a field named FirstName.  </p>
  
  <p>Any ideas?</p>
  
  <p>Suddenly my $cf7-posted_data is empty...even when I try and push the data to a session (I have sessions working on my wordpress sites) the value is empty...</p>
