    Hello,

    Thanks for reaching out to us.

    As the error suggests the data being passed to the “MMERGE1” field is invalid. I noticed that you have copied the code from MailChimp.com hosted form into our form. I would recommend deleting everything in the form and adding the fields again by using the buttons provided on top of our form at “MailChimp for WP > Forms”.

    I hope that answers your query. Let us know if you have any further questions.

    Hi,
    I have simplified the form:

    <p>
    <label>Indirizzo Email (obbligatorio)</label>
    <input type="email" name="EMAIL" required="">
</p>
<p>
    <center><label>
        <input name="AGREE_TO_TERMS" type="checkbox" value="1" required=""> <a href="https://www.enotecadadavid.it/cookie-policy/" target="_blank">Ho letto e accetto i termini e le condizioni</a>
      </label></center>
</p>
<center><p>
    <input type="submit" value="Iscriviti">
  </p></center>
<p>

    I always get the same error. The MMERGE1 field should no longer exist:

    Hello,

    Can you please go to your MailChimp.com account, and share a screenshot of the list fields?

    Sorry, I only understood now. I deleted the field on the MailChimp.com website and now everything works. Thanks
