Emails No Longer Sending After Update

Where can we see the website in question?

The site is: https://www.seeitsolved.com

Where on the site do you have the form having the issue?

At the bottom of the home page on seeitsolved.com

See Setting up mail

What email settings do you have in the Mail tab panel?

To protect personal data, hiding email addresses in the settings or replacing them with dummy addresses is strongly advised. You can also include screenshots.

Hi. I thought it would be important to note that this form was working fine until the last update with the below setting remaining unchanged.

TO: ********@seeitsolved.com,[_site_admin_email]
FROM: [_site_title] ********@seeitsolved.com
SUBJECT: [_site_title] “[your-subject]”
ADDITIONAL HEADERS: Reply-To: [your-email]
MESSAGE BODY:

From: [your-name] [your-email]
Subject: [your-subject]

Message Body:

[your-message]

This e-mail was sent from a contact form on [_site_title] ([_site_url])

The From field value is invalid. It is no surprise email is not delivered.

Can you explain why it is invalid? It is the standard field that you get when you create a new form. Not sure how that would suddenly cause it to be invalid.

See Invalid mailbox syntax is used.

I have reviewed the above documentation, and still, it does not explain why the FROM field with the default value that the plugin sets when creating a new form ( [_site_title] <[email protected]> ) is invalid.

I have even checked the validation on the form in the link provided after the most recent update. It stated that there were no invalidations.
