A child theme is required to properly implement this customization. If you are not currently using a child theme, you can download one using the following link:

https://www.dropbox.com/s/ut4dkjq5n7j9nkz/divi-child-theme-0.1.1.r20.zip?dl=1

Add the first code snippet (above) to your child theme's functions.php. Then add the second one to a new file in your child theme's directory named my-main-modules.php.

Hi, I have implement this one it's also working fine but in reviving mail no username, email address, only message came without label.

Can you guide me.
