I pressed the reset button and I deleted the subscription model Sendit

Here the HTML for you

<!– Start Sendit Subscription form –>
<div class=”sendit”>
<h4>Subscribe to our newsletter</h4>
<form name=”theform” id=”senditform”>
<!– the shortcode to generate subscription fields –>
{sendit_morefields}
<p><label for=”email_add”>Your email</label>
<input id=”email_add” type=”text” placeholder=”email here” name=”email_add”/>
<input type=”hidden” name=”lista” id=”lista” value=”{list_id}”><div id=”sendit_wait” style=”display:none;”></div>
<input class=”button” type=”button” id=”sendit_subscribe_button” name=”agg_email” value=”{subscribe_text}”/>
</p>
</form>
<div id=”dati”></div>
<small><i>You will receive an email with the confirmation link (check your spam folder if NOT)</i></small>

<small>Sendit WordPress newsletter</small>
</div>
