Error empty field – all the time

Can you post a screenshot of your FORM and MAIL configuration?

Hello,

Please find here the form : https://ibb.co/cg9W2A

Thanks a lot for your help ??

Hi. Thanks for that.

I can see one main issue:
In the Form, the form-tag for the email field is incorrectly set to a text field, instead of an email field. Change to [email* your-email watermark "Votre adresse e-mail"]

There is also one improvement you can make:
In the Mail >> Additional Headers field, add the following to allow you to reply directly to the sender using the “Reply” button in your email client (e.g. Outlook, Thunderbird): Reply-To: [your-name] <[your-email]>

Hello,

I did follow your recommandation but I still have the same message.
Here are the update Pictures :

If you have any other leads, please share it with me ??
Thanks a lot,

The configuration looks fine now. There are a few console errors, one which looks like you may have a redirect setup on submit:

www-widgetapi.js:100 Failed to execute 'postMessage' on 'DOMWindow': The target origin provided ('https://www.youtube.com') does not match the recipient window's origin ('https://renaud-mazaleyrat.fr').

Do you have code in the Additional Settings tab? Could you copy that somewhere, remove the code and save. Then test the form.
If that doesn’t help you should try ruling out a conflict by disabling all other plugins and activating the Twenty-Seventeen theme. Then test the form.

Hello,

I think it’s fixed ??
Thanks a lot for your precious help in the process.

Best regards,
Renaud.

Brilliant news.
I also just tried a test email and the form submitted correctly. ??
