Here’s how you can edit the footer in a Divi Builder:
First, navigate to the footer section
Go to your WordPress Dashboard.
Go to Divi > Theme Builder
Edit Global Footer
Then, you can edit the footer
Once you are in the footer section, you will be able to edit text, colors, media, etc.
It’s the same way you would edit a normal Divi page
Click on ... on the bottom of the page to save.
Click on the X on top of the page to exit the page.
