Mobile Menu Does not Show
Since every Divi website is different, you will need to customize Divi Mobile to your website. One problem that we have seen is that sometimes the mobile Menu does not show and the reason is that some code is missing from the header.php file.
1.) Disable Your Child Theme.
Does your mobile menu show after disabling your child theme?
2.) Add Code.
If your mobile menu does show then add
wp_body_open(); to the header.php file of your child theme.
