Form don't submite fields

Hi, I have and issue sending a form, where the submission trought POST method does not result in any data that can be captured trough the php’s global var $_POST. It stays empty.

On localhost environment it works perfectly, but online I’m facing this problem.

Here is the html code:

<form  acti name="newsletter" id="fr_newsletter"  method="POST" enctype="multipart/form-data">
 <table>
  <tr>
   <td valign="middle"><label>Nome</label></td>
   <td><input type="text" id="nome" name="nome" /></td>
   <td><label>Email</label></td>
   <td><input type="text" id="email" name="email" /></td>
   <td><input type="submit" name="submit" value="Receber News" /></td>
  </tr>
 </table>
</form>

Please, I need urgent support This website must be launched as fast as possible and it only needs this detail fixed, thanks!
