 * Hi [@willbode](https://wordpress.org/support/users/willbode/),
 * Are you still using the old Header/Footer? If you are, please switch to the new
   Header Footer Builder (HFB) and see if it fixes the issue.
 * Please let us know how you go.
 * Kind regards,
    Herman 😊

 * I use Elementor Pro and the theme builder and I verified the same thing on two
   sites so far.

 * Same problem here 🙁
 * I have activated the new Header Footer Builder but the Problem exist – Customizer
   not work!
 * And if that wasn’t enough, with the new Header Footer Builder active, my menus
   and footers are also destroyed 🙁

 * Hi [@willbode](https://wordpress.org/support/users/willbode/),
 * Are you still using the old Header/Footer or already use the new HFB?
 * [@dieter93](https://wordpress.org/support/users/dieter93/), as per the [forum guidelines](https://wordpress.org/support/forum-user-guide/faq/#i-have-the-same-problem-can-i-just-reply-to-someone-elses-post-with-me-too),
   please start your own thread. You are welcome to cross-link it with this thread,
   so we are aware of both.
 * Kind regards,
    Herman 😊
