I have done this.
I do have to [your-firstname] [your-lastname] defined in my from field and it still appears as “WordPress”
Can I see the form?
Also, what exactly do you have in the From field in the Mail section? Of course it’s not only [your-firstname] [your-lastname], right?
The form looks like
<p>Vorname (Pflichtfeld)
[text* your-firstname] </p>
<p>Nachnname (Pflichtfeld)
[text* your-lastname] </p>
<p>E-Mail-Adresse (Pflichtfeld)
[email* your-email] </p>
<p>Nachricht
[textarea your-message] </p>
<p>[submit “Senden”]</p>
The From field just contains [your-firstname] [your-lastname], cause I thought it will replace the word “WordPress” with the senders mail, as mentioned in the form and as like the Divi theme is working.
The form is working fine, apart from “WordPress” in the From field.
