Thank you Jason, I have tried to do it through the pearl way and still not working, also I have tried to leave all blank in the email object tab. I know the server is working because I upload a simple contact form generated by me and is working ok.
Universal Email 3.0.7. “Not working” link:
contacto_omd.php
The other “working” contact form link:
contact_omd.php
Also is attached the code of the working form (contact.php)
