No burger menu/drop-down on mobile?

For our plugin custom header, you should select it in Theme Customizer > Divi Ultimate Header Plugin > Header & Navigation Styling > Choose Your Custom Navigation Style, not adding it in Divi Theme Builder.

So firstly, you will need to remove the global header from Divi Theme Builder: WP Admin > Divi > Theme Builder

Then, select your custom header style in Theme Customizer > Divi Ultimate Header Plugin > Header & Navigation Styling > Choose Your Custom Navigation Style

And lastly, you get to choose your mobile hamburger menu to be slide in / fullscreen / default dropdown menu: https://divi.help/threads/for-mobile-menu-how-to-show-slide-in-or-fullscreen-menu.646/

Upon further checking, I did few steps to make it normal again.

1. As stated previously, will need to remove the Global Header in WP Admin > Divi > Theme Builder to show back the mobile menu. See screenshot below:



2. But somehow the mobile menu is still not shown. Upon further checking, you have the below custom CSS (WP Admin > Divi > Theme Options > Custom CSS) that hide it. And thus I removed it & the mobile menu display.



3. Lastly, I notice that our default custom header injection method doesn't work for your case. Might be a plugin conflict. And thus, I switched to an alternative injection method for you & it works fine now.

Here's the option for alternative injection method: https://[YOUR SITE URL]/wp-admin/customize.php?autofocus[section]=divi_ultimate_header_plugin_header_alternate_options

Additional note:

1. I would suggest you to update Divi to the latest version. Your current Divi version has several issues.

2. For the mobile menu, you can have slide in / fullscreen menu by setting this: https://divi.help/threads/for-mobile-menu-how-to-show-slide-in-or-fullscreen-menu.646/

3. Since in mobile, it's using the Divi default menu, thus to set the logo for your mobile menu, just go to WP Admin > Divi > Theme Options > Logo

4. As for the styling of the mobile menu, you can do so in Theme Customizer > Header & Navigation

5. I selected custom header style 1 in Theme Customizer > Divi Ultimate Header Plugin
**To customize header style 1 design, just go to WP Admin > Divi > DU Header - Library
