When you analyze your HTML code generated, you can see that you have a <div> inside the table and that your iframe mixte the syntax with parameters using & and &
Probably you should only use the & and not use <div> inside the table.
          <table class="contentpaneopen">
            <tr>
              <td valign="top"><p>Ecco alcune dell enostre foto. In attesa del sito:</p>
                <div class="clr"></div>
                <iframe src="
barbyblos.com/index.php?option=com_oziog...tmpl=component" width="640" marginwidth="0px" allowtransparency="true" frameborder="0" scrolling="no" class="autoHeight"></iframe>
                </iframe>
                <div class="clr"></div></td>
            </tr>
          </table>
